Slopes and line equations

Side-by-side coordinate graphs showing parallel lines with matching rise-run triangles and perpendicular lines meeting at a right angle

Straight lines are easiest to compare when written in the form y=mx+cy=mx+cy=mx+c. In this form, mmm represents the gradient and ccc represents the y-intercept.
