Which of the following statements are true regarding functions?

function is a relation in which each value of the input variable is paired with exactly one value of the output variable. The horizontal line test may be used to determine whether a function is one-to-one.

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9

2

x+10
