Calculating the Slope of a Line: Rise Over Run Explained

The video tutorial explains how to find the slope of a line. It begins by noting that the line is decreasing, indicating a negative slope. The instructor then identifies points on the line that intersect grid lines to use in the slope calculation. The slope is calculated using the rise over run method, resulting in a negative value. The video ends with unrelated dialogue not pertinent to the lesson.

What is the direction of the line from left to right?

• Downward

• Upward

• Vertical

• Horizontal

What type of slope does a line have if it decreases from left to right?

• Positive

• Negative

• Zero

• Undefined

How many points do you need to select on the grid to calculate the slope?

• Four

• Three

• Two

• One

What is the formula for calculating the slope of a line?

• Sum of y-coordinates

• Sum of x-coordinates

• Rise over run

• Run over rise

If a point goes down 3 units and to the right 2 units, what is the slope?

• 2/3

• 3/2

• -3/2

• -2/3
