Question

The table shows the amount of money a plumber charges for different numbers of hours that he works. The plumber graphed this information.

What is the slope of the line that represents this situation?

Hours worked 2 4 7 9
Amount charged ($) 96 192 336 432

Answer 1

I CAN anwers one sec

Answer 2

To find the slope of the line, you need the equation m = rise/run, where m represents slope.

What this really is: m = y^2 - y^1 / x^2 - x^1

^ represents an exponent.
/ represents division.

So pick two points.
The vertical side on the graph is the Y axis, the horizontal is the X axis.
Pick two points on the Y axis.
Pick two points on the X axis.

You didn't specify where hours worked and amount charged is on the graph, so just apply the formula.

slope = [amount charged 1] - [amount charged 2] / [hours worked 1] - [hours worked 2]
