D. 140 miles per hour

Answer 1

Graph please?

Answer 2

yeah the graph

Answer 3

Right sorry. ;p

Answer 4

rate of speed of the train = slope of the line

Answer 5

b is not right count 70 to 105 its not 70 more its less

Answer 6

The correct answer will be A.

Answer 7

exactly

Answer 8

Didn't I put A? Hold on...

Answer 9

o_o There's no need to find the slope, you can subtract, 105 - 70. However, yes. The constant rate of change is the slope.

Answer 10

You put B.

Answer 11

Woops. I guess I didn't. I meant to. I keep doing that. It's hard to type it in.

Answer 12

You may not need to find the slope, but it's always good to know how to find it and how they connect.
