Question

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

Answer 1

slope = \[\Delta y \over \Delta x\]

\[\Delta y = y_2 - y_2\]
and
\[\Delta x = x_2 - x_1\]

Answer 2

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

Answer 3

\[\Delta\] means "change in"

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

Answer 4

HAHA!
