Question 193612
I assume its y=(-2/3)x+3
:
so plot the y intecept which is (0,3) and then mark off the slope which is the  change in y which is -2 

so mark off 2 units down and then the change in x is 3 units so move 3 units to the right and plot that point. Now you have 2 plotted points (0,3) and (3,1) enough to  draw the line.
:
{{{graph(300,300,-10,10,-10,10,(-2/3)x+3)}}}
