### Lauren and Shane

## Who invented Slope?

Rene Descartes created the formula for finding the slope of a line in the early 1600s, using slope-intercept to make a grid. Slope is used for many things. Its often used in the world. To build houses, even to see how tall a tree is.

## What is the formula for Slope?

Slope-Intercept Form y=mx+b

## Here's a problem explained for you

so u have 5y+23=83 first, subtract 23 from both sides, because you have to do the inverse then u have 5y=60 then you divide by 5 on both sides, because you have to do the inverse of multiplication so you get y=12
