How do you find the correct equation? Follow these steps.
First, plug 0 in for X and solve for Y . Does the y value match what is on the graph? 0 in this case?
a. 0 = -2(0) True - This could be an answer
b. 0 = 0 + 4 False - This cannot be an answer
c. 0 = 2(0) True - This could be an answer
d. 0 = 0 - 4 False - This cannot be an answer
Now we are down to 2 possible answers A and C. Now take another point on the line, say x=-2 and repeat, does the answer match what is on the graph? (4).
a. 4 = -2(-2) True
c. 4 = 2(-2) False
As only A matches, A must be the answer. With graphing problems, when you have to find the correct equation, always choose X=0 as the first point (assuming it has a Y value) and eliminate answers. I hope this helps.
So 1 year is 12 months, you want to multiply 225 and 12 which equals 2,700 miles. 2,700 miles is the answer.
Answer:
first you take 5200 and divided by .3 = 17333.33 which is the total of the equation e minus 10600 so that means you have to take 17333.33 and add 10600 which =27933.33= E
