The strategy that he used is the distributive property.
Answer:
22
Step-by-step explanation:
5(7)=35
3(8)=24
35-24+11=22
The next answer would be 81 degrees because 180-99=81.
We can use the slope formula to find the slope between these two points:
2 - 6 / -1 - 4
-4 / -5
Because there are two negatives, they cancel out.
The slope of the line between these two points is 4/5.
