Grade 9 gradeMath subjectFree quiz

Grade 9 linear functions connect slope as a constant rate to the graph of y = mx + b. Students write equations from two points, from slope and a point, and from parallel or perpendicular conditions. Intercepts are the points where the line meets the axes, found by setting the other variable to zero.

What you practice

These are the Grade 9 Linear Functions & Modeling skills this quiz is built around.

Compute slope and write y = mx + b from a graph, table, or two points.
Find x- and y-intercepts and graph using slope and intercept.
Write the equation of a line parallel or perpendicular to a given line through a point.

A useful tip

Nonvertical parallel lines have equal slopes. For two nonvertical perpendicular lines, slopes are negative reciprocals; a horizontal line is perpendicular to a vertical line.
