Hiya!

When there are 2 negatives together, the (-) sign changes into a (+) sign.

-7 - (-2.5) ⇒ -7 + 2.5

Your answer is D. -7 + 2.5

(-7 + 2.5 = -5.5)

Hi!

Two negatives make a positive, so this can be rewritten as
-7+2.5

The answer is D. -7+2.5

Hope this helps! :)

What is the slope of the line that contains the points (-1,2) and (3,3)?

Semmy [17]

Answer:

1/4

Step-by-step explanation:

To find the slope of a line from two points we use

m = (y2-y1)/(x2-x1)

m = (3-2)/ (3--1)

= (3-2)/(3+1)
