Comparing Distance-Time Graphs and Equations

The video tutorial explains how to compare distance-time graphs and equations by examining linear functions. It covers the concept of slope or rate of change in different representations such as equations, tables, and graphs. The tutorial further explores distance-time relationships, demonstrating how to calculate the rate of change using formulas and examples. Finally, it compares the speeds of three cars using different representations to determine which is the fastest.

What is the slope or rate of change in the equation Y = MX + B?

• The variable X

• The constant term B

• The coefficient of X, M

• The variable Y

In a table, how is the rate of change determined?

• By the difference in X values

• By the sum of X and Y values

• By the difference in Y values

• By how much Y increases when X increases by one

In a distance-time graph, what does the slope represent?

• The total distance traveled

• The time taken

• The rate of change or speed

• The initial position

What is the dependent variable in a distance-time graph?

• Rate

• Speed

• Distance

• Time

How can you calculate the rate of change from the formula D = R * T?

• By subtracting time from distance

• By multiplying distance and time

• By dividing distance by time

• By adding distance and time

If a car travels 50 miles in one hour, what is its speed?

• 75 mph

• 100 mph

• 25 mph

• 50 mph

Which car is traveling the fastest if Car A travels at 50 mph, Car B at 65 mph, and Car C at 55 mph?

• All cars travel at the same speed

• Car B

• Car C

• Car A
