Answer:
a) (-3/2,0), (0,-10)
Step-by-step explanation:
y = mx + b
Change the equation to y intercept form.
-3x - 2y = 20
Isolate -2y by adding 3x on both sides.
-2y = 3x +20
Divide everything by -2
y = [tex]-\frac{3}{2}x[/tex] - 10
If you have a ti 84 plus calculator put it in the calculator:
go to y =
then press 2nd graph
then press graph
you will be at the (x,y) table
look at what (x,y) value match your choices.
Another way to solve this equation is to substitute.
a) is the correct choice
