The value of f(2) is the same as the value of f(3).
The value of f(2) cannot be compared to the value of f(3).
The value of f(2) is smaller than the value of f(3).
The value of f(2) is larger than the value of f(3).

A telephone company charges a fixed monthly rate plus a rate per megabyte of data used. The company charges $135 for 100 megabytes of data and $375 for 500 megabytes of data. An equation can be written to show the relationship between the total megabytes used (x) and the total monthly charges (y). Which of the following best describes the steps to draw the graph?

Draw a graph that joins the points (135, 100) and (375, 500) and has a slope = 0.6
Draw a graph that joins the points (100, 135) and (500, 375) and has a slope = 0.6
Draw a graph that joins the points (100, 135) and (500, 375) and has a slope = 1.67
Draw a graph that joins the points (135, 100) and (375, 500) and has a slope = 1.67

Answer 1

(B) Draw a graph that joins the points (100, 135) and (500, 375) and has a slope = 0.6

Explanation:

1. They gave us two points

(100, 135)

(500, 375)

2. We find the formula

(375, 135)

(500,100) which is 0.6
