Some body help plz it’s a test. Sad face

A) 2

Step-by-step explanation:

First of all it is a positive slope, so cross out C and D. Then do the rise/run trick. To get from point a to b you need to go up 2 and over 1. This translates to 2/1, now that 2 divided by 1 is 2.

i would need to see the dot plot : )
