Finding the slope between two points

The video tutorial explains the concept of slope as a ratio of the change in Y values over the change in X values. It demonstrates how to plot points on a graph to visualize slope and provides a step-by-step guide to calculating slope using these points. The tutorial also introduces the slope formula, explaining how to label points and apply the formula for efficient slope calculation.

What is the slope in terms of rise and run?

• The ratio of the change in Y values over the change in X values

• The product of X and Y values

• The sum of X and Y values

• The difference in X values over the difference in Y values

How do you calculate the change in Y values between two points?

• By adding the Y values

• By subtracting the Y values

• By dividing the Y values

• By multiplying the Y values

If you move from point (-4, 3) to (2, 5), how many units do you move horizontally?

• 2 units

• 4 units

• 8 units

• 6 units

What does the slope formula use to represent the change in Y values?

• Y1 - Y2

• Y2 - Y1

• X1 - X2

• X2 - X1

In the slope formula, what does X1 and X2 represent?

• Different Y values

• The same X value

• The sum of X values

• Different X values
