Question 48508
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
{{{ graph( 400, 400, -10, 10, -10, 10,-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]
