Answer:
A
Step-by-step explanation:
(2,-2)(5,7)
7-(-2)= 9
5-2= 3
9/3= 3
slope = 3
(you could also calculate the slope by just counting up how many units it goes up/down when you pick a point from the x-axis and move left/right. basically counting the rise over run)
You just change the mixed number into an improper fraction.
4 3/5
5x4=20
20+3=23
23/5
The measure of angle ABC would be 66 degrees
Certain means the event will happen.
Impossible means the event would never happen.
