So the first line that should be plotted is y=3 and the second line is 4x+y=-5. I'm trying to find the point where they intersect.
;
we know the y coordinate at intersection will 3
In the equation 4x + y = -5, replace y with 3
4x + 3 = -5
4x = -5 - 3
4x = -8
x = -8/4
x = -2
:
the point of intersection -2, 3
