a.) y = -2x + 4
x 0 1 2
y 4 2 0

b.) y = 5x � 6
x +o +1 +2
y -6 -1 +4

c.) -3x �y = 2 => y=-3x-2
x +0 -1 +1
y -2 1 -5

a.) y = -2x + 4 [Plug in random values for x]
y = -2(1) + 4 [Let (x = 1)
y = -2 + 4 [solve for y]
y = 2, so the points are (1, 2)
.
y = -2x + 4 [Plug in another random value for x]
y = -2(-1) + 4 [Let (x = -1)
y = 2 + 4 [solve for y]
y = 6, so the points are (-1, 6)
.
y = -2x + 4 [Plug in another random value for x]
y = -2(0) + 4 [Let (x = 0)
y = 0 + 4 [solve for y]
y = 4, so the points are (0, 4)
.
y = -2x + 4

.
b.) y = 5x � 6 [same process as above]
.
c.) -3x �y = 2 [First, solve for y]
-3x +3x �y = 2+3x
�y = 2+3x
�y/-1 = (2/-1) + 3x/-1
y = -2 + (-3x) [Switch the order]
y = -3x - 2 [Repeat the process as above]
