Break apart the addends to find the sum 18+21
ololo11 [35]
We break apart the first numer:

10+8

the second:

20+1

and add like this:

18+21=10+8    +  20+1

now, we can mix up the order:

18+21=10+8    +  20+1= 10+20     + 8+1

add the parts:

18+21=10+8    +  20+1= 10+20     + 8+1=30+9=39

Brainliest for correct answer<br><br> A. 2<br><br> B. -2<br><br> C. 1/2<br><br> D. -1/2
seropon [69]

Answer:

B) -2

Step-by-step explanation:

I got the slope by using two points on the line (0,7) and (4,-1)

Slope=y2-y1/x2-x1

(7--1)/(0-4)

=

8/-4

I then simplified 8/-4 to -2

You could also solve by finding the rise over run for two points on the line.

The rise is 2 and the run is -1, making it 2/-1 or -2
