Answer:

Our intercepts are (-5,0) and (0,-3)

Explanation:

Solve for y:

#5y=-15-3x#

#y=-3-(3/5)x#

Plug in 0 for x:

#y=-3-(3/5)(0)=-3#

Plug in 0 for y:

#0=-3-(3/5)x#

Solve for x:

#3=-(3/5)x#

#-5=x#

So our intercepts are (-5,0) and (0,-3)

Now we can graph these points and connect them with a line.

graph{-3-(3/5)x [-10, 10, -5, 5]}
