Coordinate Plane — Practice Problems and Worked Solutions

Turn ordered pairs into horizontal and vertical movement.

The formulas you need here

Slope between two points

What it says
How much the line climbs for each step it takes to the right.
When to reach for it
Two points, and you need the steepness or the equation of the line through them.
Watch out
Both differences must be taken in the same order. Subtracting y one way and x the other flips the sign.

This same ratio, with the two points brought together, becomes the derivative.
