Answer:

Explanation:
Slope-Intercept Form

y: range
m: slope
x: domain
b: y-intercept
We can see that the line intersects at
, which is the y-intercept. We now have:

To find the slope, we need to start at the y-intercept. We need to find another nice point we can use. There is a nice point at
. Start at the y-intercept, go down one unit, and go right four units. By doing that, you just found your slope.

We know it is negative because as the x values become greater, the y values become less.
