how can you find the slope between two points? example- (-2,-1) and (5,13)

OpenStudy (anonymous):

slope = $\Delta y \over \Delta x$ $\Delta y = y_2 - y_2$ and $\Delta x = x_2 - x_1$

OpenStudy (precal):

Most students do not see delta y over delta x until a precal or calculus course.

$\Delta$ means "change in" life lesson. $\Delta$ y means "change in y" or how you may know it, "Rise"

OpenStudy (precal):

HAHA!
