What is the slope of the line?

Answer:
-7/2
Step-by-step explanation:
The slope of a line can be defined as: [tex]\frac{rise}{run}[/tex], which can be more formally calculated as: [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where it's essentially the same thing, except the rise/run is being calculated with two points (which you already need)
So let's just say: [tex](x_1, y_1)=(-5, 5)\text{ and } (x_2, y_2)=(-3, -2)[/tex]
Plugging the values into the equation we get: [tex]\frac{-2-5}{-3-(-5)}\implies\frac{-7}{-3+5}\implies-\frac{7}{2}[/tex]
You can also just look at the graph and see that from point 1 to point 2, it "rised" -7 units, and "ran" 2 units.
Notice how the "rise" is negative? That just means it went down.
