Question 53817
Plot (0,-2)
From that point use the slope to plot a secaond point.
m or slope={{{rise/run}}}
Your slope is an integer, so think of it as being:
{{{m=5/1}}}
So from (0,-2) go up 5 units and right 1 unit and plot that point (it should be (1,3).
Your graph should look like this:
{{{graph(300,200,-10,10,-10,10,5x-2)}}}
