Question

Show your work to prove that the equation v = -4t - 2 correctly represents the function for the data in this table.

A t v table shows the following coordinate pairs: negative two comma six, negative one comma two, and zero comma negative two.

Answer 1

the first row -2 6 means that t = -2 and v = 6

Answer 2

plug those both in and see if the equation is true

Answer 3

v = -4t - 2

6 = -4(-2) - 2

6 = 8 - 2

6 = 6

so that proves that t = -2 and v = 6 make the equation true

so that row has been confirmed

Answer 4

do the same to the other rows to fully confirm the table

Answer 5

should it equal 6 everytime or how do you know if it is correct?

Answer 6

both sides should be equal when you plug in the t and v values

Answer 7

it's not going to equal 6 every time

Answer 8

okay let me do them to see if they are correct

Answer 9

ok

Answer 10

I did it and all of them matched thanks so much
