Question 121346: - Determine how many solutions exist -
Use either elimination or substitution to find the solutions (if any)
- Graph the two lines, labeling the x-intercepts, y-intercepts, and points of intersection
y = 2x + 3 and y = -x - 4

You can put this solution on YOUR website!
y=2x+3 & y=-x-4
2x+3=-x-4
2x+x=-4-3
3x=-7
x=-7/3 answer.
y=2*-7/3+3
y=-14/3+3
y=(-14+9)/3
y=-5/3 answer.
proof
-5/3=-(-7/3)-4
-5/3=7/3-4
-5/3=(7-12)/3
-5/3=-5/3
