Application of Slope Intercept

Mr. Anderson started the year with 31 flannel shirts. Each month, he buys 3 more flannel shirts. Create an equation that models Mr. Anderson's flannel shirt collection as a function of months into the year.

• y = 3x + 31

• y = 31x + 3

• y = 34x - 12

• y = 3x + 12

Mr. Anderson started the year with 31 flannel shirts. Each month, he buys 3 more flannel shirts.

If the equation that models this situation is

y = 3x + 31, how many flannel shirts will he have after 3 months?

• 31

• 34

• 37

• 40

Mr. Anderson started the year with 31 flannel shirts. Each month, he buys 3 more flannel shirts.

If the equation that models this situation is y = 3x + 31, how long will it take him to collect 46 shirts?

• 5

• 9

• 16

• 35

In the equation y=mx+b,
what does m represent?

• Nothing in particular

• The y-intercept

• The x-intercept

• Slope

The graph represents gasoline consumption when driving a certain distance in km.  What is the meaning of the slope?

• The tank started with 50 L of gasoline

• the amount of gasoline consumed per km driven

• the distance it takes to lose a Liter of gas

• the gasoline is leaking because the slope is negative.

A veterinarian student tracks the weight of a kitten, in ounces, from the age of 0 to 32 weeks. She graphs the data and determines the line of best fit is y hat = 4.03x + 3.27. What does the slope represent in this situation?

• For every week the kitten ages, we predict the kittens weight to increase by 4.03 ounces

• For every week the kitten ages, the kittens weight to increase by 4.03 ounces

• For every ounce the kitten weighs, we predict the kittens age to increase by 4.03 weeks

• The kitten gains 4.03 ounces a week
