Take the value for x or y given and put into the equation and solve for the missing part of the point.

( -2. ?) $x = -2$ y is unknown. so

# - (-2) + 2y = 6

$+ 2 + 2y = 6$ subtract 2 from both sides

$2 -2 + 2y = 6 - 2$ gives

$2y = 4$ divide both sides by 2

$2y/2 = 4/2$ equals

y =2

(0,?) $x = 0$ y is unknown so

$- 0 + 2y = 6$ so

$2y = 6$ divide both side by 2

$2y/2 = 6/2$ equals

y = 3

(?. 4) $y = 4$ x is unknown so

$-x + 2(4) = 6$ this gives

$-x + 8 = 6$ Subtract 8 from both sides

$-x + 8 -8 = 6 -8$ so

$-x = -2$ divide both sides by -1

$-x/-1 = -2/-1$ equals

$x = 2$

The points are (-2,2) ( 0, 3) ( 2, 4)
