Solving Systems by Graphing — Easy Worksheet 1

Grade 8 · MathSheets    Name: ____________________   Date: __________

Use the graph to solve each system. Write the solution as an ordered pair (x, y), or write "no solution".

How to solve

The solution of a system is the point that lies on both lines — where the graphs intersect. Read its x- and y-coordinates from the grid and check them in both equations. If the lines are parallel (same slope, different y-intercepts), they never meet, so there is no solution.

Example

Solve the system y = 2x + 1 and y = x using the graph.
