Finding the Slope from Graphs

The video tutorial explains how to find the slope of a line on a graph by connecting two points and drawing a right triangle. It covers the concepts of rise and run, and how to express the slope as a fraction. The tutorial also discusses the slopes of vertical and horizontal lines, providing examples of positive and negative slopes. Advanced examples demonstrate how to handle improper fractions and convert them to integers.

What is the first step in finding the slope of a line on a graph?

• Count the rise and run

• Draw a right triangle

• Determine if the slope is positive or negative

• Simplify the fraction

How do you write the slope once you have the rise and run?

• As a sum

• As a product

• As a fraction

• As a difference

What is the slope of a vertical line?

• Negative

• Positive

• Undefined

• Zero

What is the slope of a horizontal line?

• Undefined

• Positive

• Zero

In the example where the rise is 3 and the run is 4, what is the slope?

• 4/3

• 3/1

• 3/4

• 1/4

If a line goes down from left to right, what is the sign of the slope?

• Positive

• Negative

• Zero

• Undefined

What is the slope if the rise is 3 and the run is 2, and the line goes down from left to right?

• -3/2

• -2/3

• 3/2

• 2/3

How should you write the slope if the rise is 2 and the run is 5, and the line goes down from left to right?

• 5/2

• -2/5

• -5/2

• 2/5

When given two points on a line, what should you do after drawing a right triangle?

• Write the slope as a product
