Pre-Algebra solving systems by graphing worksheet
Draw both lines on the grid; the solution is the point they share. Every crossing here is at whole-number coordinates, so once the lines are drawn it can be read straight off the grid. Easy gives two whole slopes, medium makes one a fraction, and hard prints one line in standard form to be rearranged first.

How to do these
Graph both lines and find where they cross: and
- Draw y = 2x - 1: start at -1, up 2 across 1.
- Draw y = -x + 5: start at 5, down 1 across 1.
- They share (2, 3). Check it in both.
The answer is .
Where students go wrong
Reading the coordinates the wrong way round, or giving only one number. The answer is a point, so it needs both, and across comes before up.
Also called graphing method, intersection of two lines or systems of equations.
