Simple math, not sure how to explain it.

simplify the expression and continue from there

Step-by-step 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.
