About This Worksheet

This medium-level worksheet contains 18 problems designed for 8th Grade students practicing graphing linear functions. Medium worksheets introduce larger numbers and varied question formats to deepen understanding and build fluency.

Read ordered pairs and solve linear equations using signed arithmetic.

  • Connect functions with inputs, outputs, equations, slopes and coordinate graphs.
  • Check your result using the method in the example before moving to the next question.

How to Solve: Worked Example

Example Problem: Graph y = 1x + 1 on the grid. Use x = −1, 0 and 1 to find three points.
Solution Steps:
  1. Substitute each x-value to calculate y.
  2. Plot the three ordered pairs and extend the line.
Answer: Points: (−1, 0), (0, 1), (1, 2); draw a straight line through them.
Tip: Check your result using the method in the example before moving to the next question.
