Slope Representations

Determine the slope and y-intercept from the following equation:   y = 3/2x + 3

• slope: 5   y-intercept:  (0,3) 

• slope: 3/2   y-intercept:  (0,3) 

• slope:  3  y-intercept:  (0,3/2)

• slope: 3/2   y-intercept:  (0,5) 

Mrs. Hartshorn uses the formula y = -3x + 27 to keep track of how much money she has in her coffee fund each day (she buys one coffee each day). x is the number of days and y is the amount of money in her coffee account. What does the -3 represent in the story?

• The cost of each coffee

• What she started with in her coffee fund.

• The rule

• It means nothing. Mrs. Hartshorn just likes the number -3.
