Answer/Step-by-step explanation:

Convert into point-intercept form:

Formula:
y=mx+b


-2x+y=8


y=2x+8

Now we can graph:

y-intercept: (0,8)

slope (m): 2

To plot: m = 2/-1

then, m = -2/1 until the complete graph has a linear line.

Answer:

1. Convert the equation into point-slope form. (y=mx+b)

-2x+y=8 becomes y=2x+8

2. We can identify 8 as our y-intercept so plot 8 on the y-axis.

3. Start plotting points at 8. The slope 2x (2/1) should be plotted 2 units up and 1 unit right. Keep plotting points like this and you will achieve a linear slope.
