Question

Graph the equation by plotting three points -2y=-x+8

Answer 1

The three points are (0,-4)
(4.5,-1.75) and (8,0)

Answer 2

`-2y=-x+8\qquad\text{divide both sides by (-2)}\\\\y=(1)/(2)x-4\\\\for\ x=0\to y=(1)/(2)(0)-4=0-4=-4\to(0,\ -4)\\\\for\ x=2\to y=(1)/(2)(2)-4=1-4=-3\to(2,\ -3)\\\\for\ x=4\to y=(1)/(2)(4)-4=2-4=-2\to(4,\ -2)`
