Question

A train is traveling at a constant speed in miles per hour.Which equation models the data in the table? y=60x−80y=80x−60y = 20xy = x + 80

Answer 1

Okay, here we have this:

Let's plug in each equation x = 2 to see which ones satisfy the value of "y" from the table.

A)

y=60(2)-80=120-80=40≠100 This option is incorrect

B)

y=80(2)-60=160-60=100 This option satisfies the value of the table.

C)

y=20(2)=40≠100 This option is incorrect

D)

y=2+80=82≠100 This option is incorrect

Finally we obtain that the correct answer is the second option.
