Question

Look at this graph: 90 80 60 50 D What is the slope? Simplify your answer and write it as a proper fraction, improper fraction, or integer. Suomi Work it out

Answer 1

To calculate the slope of the line we need to take two points of the graph where the line crosses through the corners of the grid.

We can take the following points:

Now we need to find the change in x and the change in y between the points:

As we can see:

`\begin{gathered} \text{change in x=3} \\ \text{chanche in y=1} \end{gathered}`

And the slope "m" is defined as the change in y divided by the change in x:

`m=\frac{\text{change in y}}{change\text{ in x}}=(1)/(3)`

Answer: 1/3
