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)
