Graphing Real World Applications Linear Equations Review

Write the following equation in slope intercept form:

Y = MX + B

y + 2 = -3(x - 5)

• y = -3x + 17

• y = -3x + 13

• y = -3x - 13

• y = -3x - 17

Zara made an initial deposit to a bank account and then added a fixed amount every week. The table shows the money in her account. Write an equation in slope-intercept form to represent the situation.

• y = 30x + 100

• y = 20x + 120

• y = 120x + 120

• y = 50x + 100

Create a scatterplot from this data. Write the line of best fit for the data.

• y = 5.02x + 1.82

• y = 8x - 15

• y = 1.82x +5.02

• y = -1.82x +5.02

A copier machine can produce 500 copies per minute. This can be modeled by C(m) = 500m. The copier can only run for 4 hours (240 mins) before needing a break.

What is the smallest/largest the Domain can be?

A driving range charges $4 to rent a golf club plus $2.75 for every bucket of golf balls you hit. Write an equation that shows the total cost c of hitting b buckets of golf balls.

• c = 2.75b + 4

• c = 2.75b

• c =  4b- 2.75

• c = 2.75b - 4

A copier machine can produce 500 copies per minute. This can be modeled by C(m) = 500m. The copier can only run for 4 hours (240 mins) before needing a break.

What does the DOMAIN represent?

• Copies made

• minutes on

• 500

• 4 hours
