40 points a train is traveling at a constant speed in miles per hour. which equation models the data in the table? y=60x−80 y = 20x y=80x−60 y = x + 80 hours (x) miles (y) 1              20 2            100 3            180 4              260 5              340

Just trying the offered equations for x=2 will help you sort it out. You want to find the equation that gives you the table value for x=2, which is 100.

For x=2, the equations give you ...

A: 60·2-80 = 40 . . . . ≠ 100

B: 20·2 = 40 . . . . . . .≠ 100

C: 80·2 -60 = 100 . . probable answer

D: 2 +80 = 82 . . . . . ≠ 100

The best choice is the 3rd one: y=80x−60

a 360 degree rotation
