Question

How do I find slope?

The graph of a line is shown on the grid. The
coordinates of both points indicated on the graph of the
line are integers.
What is the rate of change of y with respect to x for
this line?

Answer 1

4/5

Explanation:

The two points are (5, 7) and (-5, -1). The slope is the difference of y over the difference in x, or
`(7--1)/(5--5)`. This simplifies to 8/10, or 4/5.
