Draw

Fatima has 2.5 gal of gas in her car. A pump at the gas station adds gas to her car at a constant rate. After 70 seconds, the gas tank in Fatima’s car is full, holding 12.4 gal.

Graph the amount of gas in the car’s tank versus time. Choose an appropriate scale.

Step 1: prepare the graph

Step 2: decide on the scale

Step 3: graph the line (based on known points – initial value, slope)

Draw

Kevin drives his car at a constant speed. After 10 min of driving at the constant speed, he has traveled 10 mi. After 30 min of driving at the constant speed, he has traveled 30 mi.

On the coordinate grid, graph Kevin's distance driven over time.

Water evaporates at a constant rate while boiling. After 2 min of boiling, a pot contained 3 cups of water. After 4 min of boiling, the same pot contained 2 ½

cups.

On the coordinate grid, graph the amount of water in the pot as it changes over time.

Multiple Select

Carl has a bank account he uses to withdraw money from over the course of 10 weeks. He starts with $950.

What are the appropriate scales for the axes of a graph showing the relationship between the amount of money in Carl’s account and the number of weeks?

Select each correct answer.

• The y-axis is labeled Amount of money ($) and goes by fifties from 0 to 1000.

• The x-axis is labeled Time (wk) and goes by ones from 0 to 10.

• The x-axis is labeled Time (wk) and goes by fives from 0 to 20.

• The y-axis is labeled Amount of money ($) and goes by hundreds from 0 to 500.
