Answer: See below for the graph

The graph is a straight line through (0,-8) and (1,-3)

======================================================

Further explanation:

You have the correct y intercept. This is where the graph crosses the y axis.

From this starting point, move up 5 units and to the right 1 unit. This motion of "up 5, right 1" is directly from the slope of 5 aka 5/1

slope = rise/run = 5/1

rise = 5 = how far you go up

run = 1 = how far you move to the right

So if we started at (0,-8) and moved up 5, right 1, then we would arrive at (1,-3)

Once these two points are plotted together, we can draw a straight line through them as you see below. I used GeoGebra to make the graph, but you could use Desmos (or similar) if you prefer.
