Answer:
Step-by-step explanation:
I can't draw the graph on this software, I will expalin them.
y = x + 3 a line with a slope of 1 passing through (0, 3)
that means when x = 0 y = 3
2x+y=-3 convert to y intercept form
2x+y - 2x = -3 -2x
y = -2x - 3 a line with a slope of -2 passing through (0, -3)
that means when x = 0 y = -3
You can see the TWO lines intersect at (-2, 1)
