You have to divide both sides by 12 so 12f/12 =24/12 is f = 2
Bottom answer is correct: d {0, 1, 2, 3}, r {-5, -2, 3, 4}, relation is a function
we have

we know that

and

substitute in the expression



therefore
<u>the answer is</u>

Do you mean y = mx + b instead of y = mc + b? In that case:
b in y = mx + b format is the y-intercept, as this kind of equation is called slope-intercept form.
The answer is a all of the points
