M6 Lesson 2

Review from Yesterday

Modeling Functions with Equations, Graphs, or Tables

Multiple Choice

An internet company charges a flat fee of $25 and $0.01 per minute.

Write an equation to represent the situation with y being the total cost and x being the number of minutes.

• y = 0.01x + 25

• y = 25x + 0.01

Multiple Choice

Match the scenario to the equation:

y = 0.20x + 1.30

• A company charges a flat rate of $0.20 and $1.30 per minute.

• A company charges a usage charge per minute of $0.20 and a flat rate of $1.10

• A company charges a usage charge per minute of $0.20 and a flat rate of $1.30

Matching Graphs to Equations

Review of the Review from Yesterday

Where do you see the y-intercept from the equation below on the graph?

y = 3x - 2

Where do you see the slope from the equation below on the graph?

y = 3x - 2
