What does it mean to solve a system of equations like y=x^2+4x-5 and y=x-1 graphically?

Answer 1

graph the first equation, which is parabola, and has x-intercepts of -5 and 1, opening upwards

the second equation is a straight line with slope 1 and y-intercept of -1

my rough sketch shows them intersecting at two points.

the intersection of the the two graphs is the "solution to the system" of equations.
