Reading y = mx + b

Printable practice with an answer key the engine computes, at three levels, in as many versions as you need.

Problem types

• read the slope: y = 3x − 4: slope
• read the y-intercept: y = 3x − 4: the y-intercept is (0, b). b =
• slope with no number showing: y = x + 5: slope
• find the x-intercept: y = 2x − 6: the x-intercept is (a, 0). a =
• terms in the other order: y = 4 − 3x: slope
