Question

Which equation represents a linear function?

Equation 1: y = 2x2 + 1
Equation 2: y2 = 3x + 1
Equation 3: y = 5x − 1
Equation 4: y = 4x4 − 1

Equation 1
Equation 2
Equation 3
Equation 4

Answer 1

Am I right with C?

Answer 2

yep

Answer 3

remember that linear equations are in the form of y=mx+b, m=slope, b=y-intercept

Answer 4

@AZ do you agree?

Answer 5

just making sure lul

Answer 6

Yes, if I disagreed I would have replied to get you back on the right track :)

Answer 7

Oh ok, thank you

Answer 8

but essentially, linear functions will have x to the power of 0 or 1

the other answer choices had x^2, x^3, x^4
those aren't linear lines

Answer 9

True, yeah
