Answer:

-8/5

Step-by-step explanation:

The thing that makes lines different from other kinds of curves is their <em>constant rate of change</em>. We call this rate of change <em>slope</em>, and you usually see it represented with the letter <em>m</em>. We measure it as the rate our y-coordinate changes for some amount our x-coordinate changes.

We're given the two points (-1, 4), and (4, -4). From that first point to the second one, our x-coordinate <em>increases </em>by 5, while our y-coordinate <em>decreases </em>by 8, so our change in y is -8 for every 5 in the positive x direction, and we'd write our slope as

m = -8/5
