Answer: (16,3) and (4,0)

Explanation:

Using the equation x-4y=4 is asking what is the value of x if the value of y is 3. So plot it into the equation and solve for x.

x-4(3)=4 multiply the left side

x - 12 = 4 add 12 to both sides

x= 16

You will now have the coordinates (16,3)

In the second pair it gives the x coordinate which is 4 but we need to solve for y.

4 - 4y=4 subtract 4 from both sides

-4 -4

-4y = 0 Divide both sides by 4

y = 0

The ordered pair will be (4,0)
