Question

What is the equation of a vertical line passing through the point (−5, −1)?

y = −5

y = −1

x = −5

x = −1
Carlos was tracking the increasing number of people walking down the street. At 6 a.m. there were 57 people. At 8 a.m. there were 65 people. If Carlos made the function f(x) = 4x + 33, what would the 33 represent?

The rate at which the number of people was increasing

The length of time he recorded for

The number of people at midnight (Maybe this one?)

The total change in the number of people

Answer 1

I believe it is The total change in the number of people.

Answer 2

I thought that to...because its not the rate they increase for sure, and the length of the time he recorded fro doesn't make scene.

Answer 3

Wipe out the junk answers.

Answer 4

As in get rid of the ones that you know aren't right

Answer 5

lol yeah I think your right on the second one...know I need help with the first one

Answer 6

vertical means it goes up/down parallel to the y axis

so regardless of y, the solution will always be on the same x
f(y) = x
f( doesn'tmatter ) = -5

Answer 7

So x=-5?

Answer 8

yes

Answer 9

oh i forgot that thank you for reminding me!

Answer 10

Thank you! ^_^...Thanks for drawing up a graph to...it really helped

Answer 11

because (-5, -1) is one of the point

other points on that vertical line would be
(-5, -3), (-5, 2) and (-5, 7)
