This short worksheet reviews the slope formula, the point-slope form of a line, and the slope-intercept form of a line.
I use this as a preview assignment for Calculus students before they begin to investigate secant lines and tangent lines, usually assigning it the night before the lesson and then, depending on the students, either going over it at the beginning of class or letting the students self-check with the answer key.
It could also be used in Algebra 1, Algebra 2, Geometry, or Precalc
