\[Slope=\frac{y_2-y_1}{x_2-x_1}\]

You cant take any two points
You've to choose the points from the graph given
Here as you can see points are (-1.5,0) & (0,-3)

Did my didi sweep twight?

OpenStudy (diyadiya):
The points are (7.5,0) & (0,-5) (the line is passing through -5 not -3)
Yes,Same formula for everything!

okay i got -5
-----
-7.5 what do i do next?
