My book is showing the solution for graphing a system of linear equations
y > 2x  7
y is greater than or equal to 3x + 7
I see the way they graphed it and both lines intersect at one point. Did the just find 7 and +7 on the line in order to graph or did they solve for y and find x in order to fingure out how to graph these two equations. I'm lost.
