Question

Which equation represents a linear function?
A. y – 2 = –5(x – 2)

B. x + 7 = –4(x + 8)

C.y – 3 = y(x + 4)

D.y + 9 = x(x – 1)

Answer 1

You are looking for the equation this is in this form:

y=mx+b where m is the slope and b is the y intercept

Answer B is missing a y variable so its not a linear equation.

Answer C is missing an x variable so its not a linear equation

Answer D the x variable is squared when you multiple x(x-1) so its not a linear equation
