Sketching Graphs

​A bus was stopped for three minutes at a bus stop. When the light turned green, the bus accelerated at a steady rate, then continued driving at a constant speed. Then, the driver decelerated until it came to a stop at the next bus stop to pick up more passengers. Sketch a graph to represent the situation described.

​Sketching Graphs

​Step 1: Label your axes

Multiple Choice

We are labeling the axes time and speed. What units should we use?

• minutes and miles per hour

• hours and kilometers per hour

• weeks and meters per hour

• minutes and miles per second

​STEP 1: Label your axes.

STEP 2: Mark up each phase or interval

given. Determine:

•Are we increasing, decreasing, or

staying constant?

•How quickly are we increasing or

decreasing? (How steep should the

line be?)

•What direction are we traveling?

Multiple Choice

What will the graph look like here?

• There is no way to determine what the graph is doing.

• The graph will be a straight line on the y-axis.

• The graph hasn't started yet.

• The graph will be a straight line on the x-axis.

Multiple Choice

What will the graph look like here?

• There is no way to determine what the graph is doing.

• Up at a diagonal

• Straight on the x-axis

• Straight, but not on an axis

Multiple Choice

What will the graph look like here?

• There is no way to determine what the graph is doing.

• Up at a diagonal

• Straight on the x-axis

• Straight, but not on an axis

Multiple Choice

What will the graph look like here?

• There is no way to determine what the graph is doing.

• Along the x-axis

• Going down

• Straight, but not on an axis

Multiple Choice

When a pizza oven is turned on, it starts heating at 100 degrees. It increases

temperature at a constant rate until it reaches 450 degrees, then stays on for a few

hours. When it is turned off, it decreases temperature at the same rate it heated

at, until it is completely cooled. Which graph below best represents this scenario?
