Answer:
The answer is D
Step-by-step explanation:
A cant be right because the graph isn't a straight line.
B cant be right because from 0 to 60 the graph the line goes at a(n) upward slope not a straight line.
Although the first part of question c is right, the second part is wrong. From 50-90 the ling goes at a downward slope via decreasing, which isn't equal like it said so question C is wrong.
So the correct answer is D
i think the answer would be B but im not 100% sure
4, 2, -x ^, -x it goes from the highest number then letter with any sign attached

Next step is to move the
x
term to the left side of the equation by subtracting
1
x
from each side of the equation:
−
