1) -2

2) 0

3) 12

Explanation

y = 1/4x, in order to obtain the y value you substitute the x value into the equation.

When x = -8

y = 1/4 • -8 = -2

When x = 0

y = 1/4 • 0 = 0

When you want to obtain the x value, rearrange equation then substitute the y value

y = 1/4x

Multiply both sides by 4

4y = x

When y = 3

3 • 4 = 12

Answer:

x y

8 -2

0 0

12 3

Explanation:

The equation you are given is:


y = (1)/(4)x

To find y, replace the given x-value in the table with x in the equation, and solve for y.

When x = -8, you get, replacing x with -8:


y = (1)/(4)(-8)

Simplify:


y = -2

This gives you the line in the table:

-8 -2

When x = 0, you get, replacing x with 0:


y = (1)/(4)(0)

Simplify:


y = 0

This gives you the line on the table:

0 0

To find x, replace the given y-value in the table with y in the equation, and solve for x.

When y = 3, you get, replacing y with 3:


3 = (1)/(4)x

Simplify:


3 * 4 = (1)/(4)x * 4


12 = x

This gives you the line in the table:

12 3
