Practice Linear Functions in Math
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
A function whose graph is a straight line, characterized by a constant rate of change between any two points.
Every step right changes y by the same amount—like climbing stairs at a constant pace.
Example 1
easyWrite the equation of a line with slope 2 and y-intercept -3.
Example 2
mediumFind the equation of the line through (1, 3) and (4, 12).
Example 3
mediumWrite the equation of a line with slope 3 that passes through (1, 7).
Example 4
easyWhat are the slope and y-intercept of y = -5x + 7?
Example 5
hardConvert 3x + 2y = 12 to slope-intercept form.
