Calculating Slope and Rise

The video tutorial explains how to determine the slope of a line passing through two points. It covers two methods: a graphical approach using the rise over run concept and an algebraic approach using the coordinates of the points. The slope is calculated as the ratio of the vertical change (rise) to the horizontal change (run) between the points. The tutorial demonstrates both methods, showing that the slope is 3 in this example.

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

• Calculate the midpoint

• Find two points on the line

• Draw a perpendicular line

• Identify the y-intercept

How is the 'run' of a line determined on a graph?

• By calculating the area under the line

• By finding the midpoint

• By counting the horizontal spaces between two points

• By measuring the vertical distance

What is the significance of the scale in determining the rise?

• It helps in finding the midpoint

• It determines the slope directly

• It affects the calculation of the rise

• It is used to find the y-intercept

What is the slope of a line if the rise is 12 and the run is 4?

• 4

• 5

• 3

• 2

Which formula is used to calculate the rise algebraically?

• x1 + x2

• y1 + y2

• y2 - y1

• x2 - x1

What are the coordinates of the first point used in the algebraic method?

• (5, 16)

• (1, 4)

• (0, 0)

• (2, 8)

How is the 'run' calculated using coordinates?
