Understanding Linear Graphs and Slope

What does the 'm' represent in the linear equation y = mx + b?

• The time in minutes

• The x-axis

• The slope of the graph

• The y-intercept

How do you calculate the slope of a line on a graph?

• By finding the y-intercept

• By counting the number of grid squares

• By dividing the rise by the run

• By measuring the length of the line

If the rise is 20 and the run is 2, what is the slope of the line?

• 20

• 10

• 5

• 2

What is the equation of the graph if the slope is 10 and there is no y-intercept?

• y = x + 10

• y = 0x + 10

• y = 10x + 0

• y = 10x

In the context of the video, what does the variable 't' represent?

• Temperature in Celsius

• The slope of the graph

• Time in minutes

• The y-intercept
