MR Collins made a scatter plot to show the relationship between the number of absences a student in her class has the student final exam score
Determine the equation for the line that passes through (2,-1) and (6,5)
Write in point slope form
Write in slope intercept form
Write in standard form
Answer with explanation:
The equation of a line passing through (a,b) and (c,d) is given by :-
[tex](y-b)=\dfrac{d-b}{c-a}(x-a)[/tex]
Equation of line passing through (2,-1) and (6,5) is given by :-
[tex](y-(-1))=\dfrac{5-(-1)}{6-2}(x-2)\\\\\Rightarrow\ (y+1)=\dfrac{6}{4}(x-2)[/tex]
[tex]\\\\\Rightarrow\ (y+1)=\dfrac{3}{2}(x-2)\ \ \ \ \ \text{[point slope form} : (y-y_1)=m(x-x_1)] \\\\\Rightarrow\ y+1=\dfrac{3}{2}x-3\\\\\Rightarrow\ y=\dfrac32x-4\ \ \ \ \ [\text{ slope intercept form} : y= mx+c]\\\\\Rightarrow\ 2y= 3x-2\times4\\\\\Rightarrow\ 2y=3x-8\\\\\Rightarrow\ 3x-2y=8 \ \ \ \ [\text{Standard form : Ax + By = C}][/tex]

Answer:
rate of change is -1/3 (table) and 4 (graph)
Function 2 has the greater rate of change because the graph is steeper, and |4| is bigger than |-1/3|
Step-by-step explanation:
Answer:
(a) Function 1 : -2 Function 2 : 3.
(b) Function 2
Step-by-step explanation:
For function #1, you can calculate the rate of change (another word for slope) by counting the change between each y value. So, when x is 2, y is -3. When x is 3, y is -5. The rate of change is -2!
Show your work by marking an arrow for each y and writing -2.
Function #2, you need to find the slope (rate of change) by drawing a rise/run line when the equation line hits a point on the graph. One point is (-1,1) another point is (0,4). The slope/rate of change is 3.

If point E is the midpoint of segment AC and point D is the midpoint of segment BC, which expression represents the value of u?
A. u equals p over q
B. u = 1/2s
C. u equals q over p
D. u = 2s
Answer:
last answer D
i took the test
The expression that most effectively represents u's value would be:
D). u = 2s
What is expression?An expression is a sentence with a minimum of two numbers or variables and at least one math operation.
Given that,
In ΔABC, E is the midpoint in the segment AC and D is the midpoint of BC.
Now,
CE = 0.5 × AC(midpoint)
CD = 0.5 × CB (midpoint)
Thus,
CE/AC = CD/CB = ED/AB = 1/2
As ED = s and AB = u
So, u = 2s

How many solutions does the equation 2(9x−6)=18x+2 have?
A.Infinitely many
B.No solution
C.Number of solutions cannot be determined
D.One solution
Answer:
no solution
Step-by-step explanation:
first you have expand the equation and so you will get
18x-12=18x+2
after you cancel 18x on both sides and so you will get
-12=2
and since that equation is false you will get
no solution
11. A tank is being filled up with water. At t=0, we know that the tank holds 150 gallons of
water, and after one hour ( t=1) , it holds 180 gallons of water.
a) Assuming that the volume of water in the tank, V, is a linear function of time, t, in hours,
find a formula for V ( linear function)
b) BY what percent did the volume of water increase from t=0 to t= 1?
Answer:
V = 30t + 15020%Step-by-step explanation:
Given
Initial volume = 150 galVolume after 1 hour = 180 gala) The volume formula will be:
V = 30t + 150As 150 is y-intersect (volume at zero time) and the rate of change (the slope) is 30 gal per hour
b) Increase of volume by percent:
30 gal increase on top of 150 gal
30/150*100% = 20%Answer:
20%
Step-by-step explanation:
The volume formula is V = 30t + 150 → where 150 is y-intersect and the slope is 30 gals per hour
So you can do:
30 gals of increase on top of the 150 gals to get:
30/150×100% which equals 20%

Jared and Pedro walk 1 mile in about 15 minutes. They can keep up pace for several hours. About how far they walk in 65 minutes
Jared and Pedro walked a total of 4.3 miles
Step-by-step explanation:The equation for distance is speed = distance ÷ time.Rearrange the equation to make distance the subject:(multiply both sides by time)
Distance = Speed × Time
Convert your numbers into suitable units:1 mile ÷ 15 = 0.06m/minute
Finally, substitute the numbers into the equation and solve:Distance = 0.06 × 65 = 4.3miles (rounded to the nearest decimal place)
Proving the Sum of the Interior Angle Measures of a Triangle Is 180
The sum of the interior angles of a triangle is 180° is proved below.
We are given that;
To prove angle sum property of triangle
Now,
There are different ways to prove that the sum of the interior angles of a triangle is 180°. Here are three common proofs:
Proof : Using parallel lines and alternate interior angles
Since the line PQ is parallel to the side BC, and AB and AC are transversals, we can use the property that alternate interior angles are congruent.
Therefore, we have:
∠QAC = ∠ACB
∠PAB = ∠ABC
Adding these equations, we get:
∠QAC + ∠PAB = ∠ACB + ∠ABC
But ∠QAC + ∠PAB is a straight angle, which measures 180°. So, we have:
180° = ∠ACB + ∠ABC
Adding ∠CAB to both sides, we get:
180° + ∠CAB = ∠ACB + ∠ABC + ∠CAB
Simplifying, we get:
180° = ∠ACB + ∠ABC + ∠CAB
Hence, by the triangles the answer will be given above.
