The video tutorial explains how to compare ratios using graphs by examining the steepness of lines. It demonstrates that the steeper the line, the greater the ratio. The tutorial also covers how to determine unit rates by identifying where lines cross the x-axis or by using specific points on the graph. Examples are provided to illustrate these concepts, showing how to calculate unit rates using both methods.

What is the primary purpose of graphing ratio tables on a coordinate plane?

• To calculate the area under the curve

• To visually compare the steepness of the lines

• To find the intersection point with the y-axis

• To determine the color of the lines

How can you determine which ratio is greater when looking at two lines on a graph?

• By counting the number of points on each line

• By checking which line is steeper

• By comparing the length of the lines

• By measuring the distance between the lines

What does a steeper line on a graph indicate about the ratio?

• The ratio is smaller

• The ratio is negative

• The ratio is greater

• The ratio is equal

Where do you look on a graph to find the unit rate of a line?

• At the highest point of the line

• At the origin

• Where the line crosses the x-axis

• Where the line crosses the y-axis

What is the unit rate of a line that crosses the x-axis at (1, 4)?

• 3

• 2

• 4

• 1

How can you find the unit rate using a specific point on the graph?

• By adding the x and y values

• By multiplying the x and y values

• By subtracting the x value from the y value

• By dividing the y value by the x value

If a point on line G is (2, 8), what is the unit rate?

• 2

• 3

• 4

• 5

What is the unit rate for line F if it crosses the x-axis at (1, 2)?

• 1

• 2

• 3

• 4

How can you verify the unit rate of a line using a point like (2, 4)?

• By multiplying the coordinates

• By dividing the y-coordinate by the x-coordinate

• By adding the coordinates

• By subtracting the x-coordinate from the y-coordinate

What is the unit rate for a line if a point on it is (2, 4)?

• 2

• 3

• 1
