Question

Solve the system of equations alphabetically. Verify your answer using the graph. y = 4x -5, y =-3

Answer 1

So, since both equate to y, we can solve for x by equating the equations to each other. 
4x - 5 = -3
So: 4x = 2
So: x = 1/2, or 0.5
Now, y = -3, so the solution is (0.5, -3)
You can graph the two equations, and the point where they meet will be (0.5, -3).
