Question

Which of the following has a graph that is a straight line?
Equation 1: y = 4x3 + 6 Equation 2: y = 5x − 4.5 Equation 3: y2 = x − 1 Equation 4: y = 2x2 + 6

Answer 1

If you could help me on a few that's would be great!

Answer 2

Which equation has x or y that is \(not\) to the power of something?

Answer 3

Where neither one is to the power of something I mean ;)

Answer 4

Hm, Maybe the 2nd one? :o

Answer 5

Ding ding ding, we have a winner! :D

Answer 6

OMG, Thanks!!!!

Answer 7

I've got one more, Which statement best explains whether y = 2x − 3 is a linear function or a nonlinear function?
It is a linear function because the graph contains the points (0, −3), (1, −1), (2, 1), which are on a straight line. It is a nonlinear function because the graph contains the points (0, −3), (1, −1), (2, 1), which are not on a straight line. It is a linear function because the graph contains the points (−3, 0), (−1, 1), (1, 2), which are on a straight line. It is a nonlinear function because the graph contains the points (−3, 0), (−1, 1), (1, 2), which are not on a straight line.
Don't tell me the full answer I want to figure it out like the last one!

Answer 8

Try posting each question in a new post ;)

Answer 9

But all you need to do is plug in the points and solve and the points that make the equation equal, then that is the correct answer. :) You can already tell it is ______ because it is not squared or anything ;)

Answer 10

Thank you, You've been a big help. :)
