Question

Not sure how to solve this

Answer 1

Answer:

x     y

8     -2

0     0

12    3

Step-by-step explanation:

The equation you are given is:

$y = \dfrac{1}{4}x$

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:

$y = \dfrac{1}{4}(-8)$

Simplify:

$y = -2$

This gives you the line in the table:

-8     -2

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

$y = \dfrac{1}{4}(0)$

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:

$3 = \dfrac{1}{4}x$

Simplify:

$3 \times 4 = \dfrac{1}{4}x \times 4$

$12 = x$

This gives you the line in the table:

12     3

Answer 2

Answer

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
