Answer:
Since this is time and cost, we have no need for negatives, so we begin our graph at the origin (0, 0). At 0 minutes, the cost would be $2.00, so 2 is our y-intercept. For each successive minute, the cost goes up $3, so we go from (0, 2) to (1, 5), then to (2, 8), etc.n:

Answer:
A: 114, B: 84
Step-by-step explanation:
Let A be weight of Train A, B be weight of Train B. Since A is heavier than B by 30 tons, A = B + 30. Since A + B = 198, you can substitute for A to get (B+30) + B = 198. Then simplify so 2B = 168 and B = 84.
Then plug B into A = B+30 to get A = 114.
