Answer:

The correct linear equation is;

f(x) = 10x + 8

Step-by-step explanation:

To choose the correct linear function, we just need to take a specific point, then substitute in each of the equations given to get the one right

The correct one will be the one in which when the x-value is substituted, we will get the y-value

Let us pick (1,18)

Let us begin testing;

A. f(x) = 10x + 8

f(1) = 10(1) + 8 = 10 + 8 = 18

Let us use another point to test this

The second point is (1.5,23)

f(1.5) = 10(1.5) + 8

= 15 + 8 = 23
