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

Which statement is correct?A:A horizontal line has no slope.
B:A vertical line has a slope of zero.
C:A line that rises from left to right has a positive slope.
D:A line that falls from right to left has a negative slope.

Answers

Final answer:

The correct statement is B. A vertical line has a slope of zero.

Explanation:

The correct statement is option B: A vertical line has a slope of zero. A slope of zero means that there is no relationship between x and y. Graphically, the line is flat, with zero rise over the run. A vertical line goes straight up or down and has no change in the x-coordinate, resulting in a slope of zero.

For Example: Consider the equation x = 2. This represents a vertical line that passes through the point (2, y) for any value of y. Since the x-coordinate does not change, the slope is zero.
