(3, - 2)
given y = - 2, then
- 2x + 4 = - 2 ( solve for x )
subtract 4 from both sides
- 2x = - 6 ( divide both sides by - 2 )
x = [tex]\frac{-6}{-2}[/tex] = 3
The coordinate that completes the solution to the equation is (3, -2)
Given the function y = -2x + 4
We are to find the value of x if y is -2
Substitute y = -2 into the function as shown:
-2 = -2x + 4
Subtract 4 from both sides
-2 - 4 = -2x + 4 - 4
-6 = -2x
x = 6/2
x = 3
Hence the coordinate that completes the solution to the equation is (3, -2)
