Answer:

-1/2

Step-by-step explanation:

use the slope formula:

(2-4)/(2-(-2)) = -2/4 = -1/2

you can also look at the graph and see it rises -2 (negative means goes DOWN 2) and runs 4, and the slope is rise/run, so it would be -2/4 which simplifies to -1/2

Answer:

The slope is negative one half.

Step-by-step explanation:

Slope is defined as rise over run, or Δx/Δy, when going left to right. In this case, the line goes from (-2,4) to (2,2), so the slope is:

$\frac{2-4}{2 - (-2)} \\\frac{-2}{4}\\= \frac{-1}{2}$

Answer:

Option C

Step-by-step explanation:

If a line passes through a point, then that point is called a solution to the line's equation. Substituting the x and y values of that solution into the equation will give a true statement. So, to find out which option is correct, we can substitute the x and y values of (-4.5, 10) into each equation and see if the result is a true statement.

Let's try this with option C. To make things easier, convert -4.5 into decimal form: $-4\frac{1}{2}$ . Substitute $-4\frac{1}{2}$ for x and 10 for y in the equation, then solve:
