Question

Which of the following equations represent relationships where y is a linear function of x? SELECT ALL THAT APPLY A)2x + 3y = 6B)Y = 5C)X = 1D)y = 10 - xE)y = x^2 + 5x + 6F)y = -x

Answer 1

D) and F)

Explanation

Step 1

a linear function has 1 as the exponent of the variable, so we can discand option E)

Step 2

y is a function of x, it means that y depends on x ,

then, the equations that fit this

$\begin{gathered} f(x)=y \\ y=f(x) \\ D)\text{ y=10-x} \\ F)y=-x \end{gathered}$

D) and F), because B and C does not depend on x
