Simplify your answer and write it as a proper fraction, improper fraction, or interger

2

Step-by-step explanation:

Take any 2 points on the graph,

(50, 10) & (90, 90)

Use the slope formula:

= (90-10)/(90-50)

= (80)/(40)

= 2

Hence, the slope is 2.

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
