Is 5 - (-3) equal to 8 or -2. And if one or the other, please state why one is correct and the other isn't.

Answers

Answer 1

Answer:

two negatives make a postive as they cancel each other out

5 - - 3 = 5 + 3 = 8

the only way the answer could be - 2 is if the original question said 5 + - 3 = - 2

Slope of (-2-7)(3,5)

Answers

To find the slope $ m $ of the line passing through two points, you can use the formula:

\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]

Where:
$ (x_1, y_1) $ is the first point.
$ (x_2, y_2) $ is the second point.

Given the points are:
$ (x_1, y_1) = (-2, -7) $
$ (x_2, y_2) = (3, 5) $

Plug in the values:

\[ m = \frac{5 - (-7)}{3 - (-2)} \]
\[ m = \frac{12}{5} \]
\[ m = 2.4 \]

So, the slope of the line passing through the points (-2,-7) and (3,5) is 2.4.

The equation to find slope is basically;
Rise/Run or (y2-y1)/(x2-x1)

And the answer of this problem will equal when the point are put into equation;
=12/5

So your slope is 12/5!
