Find the average rate of change of a function that contains the points (-2,3) and (2,5).

1/2
-2
2
-1/2

1 / 2

Step-by-step explanation:

The average rate of change is the same as the slope.

Slope formula: (y₂ - y₁) / (x₂ - x₁)

= (5 - 3) / (2 - (-2))

= 2 / 4

= 1 / 2

1/2

Step-by-step explanation:

The rate of change is found by

y2-y1

x2-x1

5-3

2- -2

2/4

1/2

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
