Exploring the Slope Formula

What is the learning goal for this video?

• To understand the concept of rise over run

• To learn how to calculate slope using the slope formula

• To memorize the value of the slope

• To understand the concept of coordinates

What is the slope formula?

• m = X1 - X2 / Y1 - Y2

• m = Y2 - Y1 / X2 - X1

• m = X2 - X1 / Y2 - Y1

• m = Y1 - Y2 / X1 - X2
