Question

How to calculate slope between points (5,-10) and (-12,20) algebraically??

Answer 1

its in the (x,y) form.. all you have to do is subtract y coordinates and x coordinates and divide them
its like [20-(-10)]/ [-12-5]

Answer 2

is that all I have to do?

Answer 3

yes!and you get the slope. it is related to derivatives.. learn more! theres a lot of stuff ahead... and trust me, its fun!

Answer 4

\[m = (Y _{2} - Y _{1})\div (X_{2} - X_{1})\]

where:
m = slope
