Question 790884
{{{y=(3/4)x-4}}}


generate points for this line
Plug x=4

x=4 , y = -1  (4,-1)
y=(3/4)*4-4
=3-4=-1

x=-4,y=-4 (-4,-7)

x=8,y=2 (8,2)

Plot these points and draw the required line

{{{drawing(300,300,-10,10,-10,10,grid(1),circle(4,-1,0.3),circle(-4,-7,0.3),circle(8,2,0.3),graph(300,300,-10,10,-10,10,y=(3/4)x-4))}}}
