Find the slope<br><br><br> Thxxxx

Helga [31]

Answer:

-The slope:

$m = \frac{3}{2}$

Step-by-step explanation:

-To find the slope, you need this trick:

$m= \frac{rise}{run}$

-So, according to the graph, start to the first doted point which is (0,1) to get to the second doted point, which is (2,4) on the graph, by counting how far up and how far across:

Rise: 3

Run: 2

$m= \frac{3}{2}$

So, therefore the slope is $\frac{3}{2}$ .
