the y intercept is where the line crosses the y axis, this is also when x=0
the x intercept is where the line crosses the x axis, this is also when y=0
to find them, set to zero each and find the other value
y intercept, set x=0
y=-2(0)-3
y=0-3
y=-3
y intercept is y=-3 or (0,-3)
x intercept is when y=0
0=-2x-3
add 3
3=-2x
divdie by -2
-1.5=x
x intercpet is (-3/2,0) or x=-3/2
