Basically all you need to do is estimate what 32.7 x 2.8 is. If what you get is close to 91.56, then Tom's answer is reasonable. If what you get is not close to 91.56, then his answer is not reasonable. Do you know how to estimate by rounding?
The two labeled angles are alternate exterior angles, and as such, they are equal. This means that we can set up and solve the following equation:
Write 3 four times and multiple them together. Then, write out 5 two times and multiple it together. Whatever those two answers are, subtract them
Answer:
The slope would flip along with the sign so it would be 2x
C because 8- -1 = 9 and when flipped the end is -1 and the end non flipped is 8
