Finding the Slope from a Graph

The video tutorial explains how to find the slope of a line on a graph. It begins by defining the slope as the ratio of rise over run, where rise is the vertical change and run is the horizontal change. The instructor selects two points on the line and calculates the rise by determining the vertical distance between the points, which is negative five. Then, the run is calculated as the horizontal distance, which is six. By substituting these values into the rise over run formula, the slope is determined to be negative five over six.

What is the definition of the slope of a line?

• The horizontal distance between two points.

• The sum of the vertical and horizontal changes.

• The ratio of the vertical change to the horizontal change.

• The vertical distance between two points.

What does 'rise' refer to in the context of slope?

• The horizontal direction of the line.

• The angle of the line.

• The total length of the line.

• The vertical direction of the line.

How many points do you need to pick on the line to determine the slope?

• Four

• Two

• One

• Three

If you move down five units from one point to another, what is the rise?

• 0

• -5

• 5/6

• 5

If you move to the right six units from one point to another, what is the run?

• 5/6

• 0

• 6

• -6

What is the slope if the rise is -5 and the run is 6?

• -5/6

• -6/5

• 6/5

• 5/6
