Question

What is the slope of the points (-2,7) and (2,-5)?
4
-3
-12
3

Answer 1

Answer:

The slope of a line that goes through both $(-2,\, 7)$ and $(2,\, -5)$ would be $(-3)$.

Step-by-step explanation:

The slope of a line is the ratio between rise and run between these two points.

The rise between two points is the change to the corresponding $y$ coordinates. Between $(-2,\, 7)$ and $(2,\, -5)$, the rise would be $(-5) - 7 = (-12)$ (subtract the first $y\!$-coordinate from the second.)

The run between two points is the change to the corresponding $y$ coordinates. Between $(-2,\, 7)$ and $(2,\, -5)$, the rise would be $2 - (-2) = 4$ (likewise, subtract the first $x$-coordinate from the second.)

Hence, the slope of this line would be:

$\begin{aligned} \frac{\text{rise}}{\text{run}} &= \frac{-12}{4} = -3\end{aligned}$.

Answer 2

It would be 3 you can find it on your Calcator
