Christine is finding the sum; 28(-15)+22 A: what property of addition could christine use to write the integers in a diffrent or
Flauer [41]

Step-by-step explanation:

I'm sorry if my terminology isn't correct because I've learnt it slightly differently, but what I'm assuming is this:

For A, you can rewrite the integers as 28-15+22 as a + and a - next to each other result in a subtraction.

For B, you simply do 15+22 is 37 and 28-37 is -9 due to BIDMAS (or PEDMAS if you're American).

Find the slope of the line that passes through (2, 12) and (6, 7).
Elodia [21]

Answer:

m=\frac{1}{4}

Gladly!

To find the slope, we need to find the change between <em>point a</em> and <em>point b</em>

With the difference between x1 and x2 being 4, and the difference between y1 and y2 being 1, we get a fraction that looks like this,

\frac{1}{4}

This right here is the slope of the line. Hope this helps!
