Which function equation represents the table? A. f(x) = -x + 2
B. f(x) = -3x + 2
C. f(x) = 2x + 3
D. f(x) = 3x + 2
Which function equation represents the table? A. f(x) = -x - 1

Answers

Answer 1
Answer: The answer is D. f(x) = 3x+2

This is because this is the ONLY function equation that works for ALL of the ordered pairs listed in the table

-4 = 3(-2) + 2
-4 = -6 +2 
-4 = -4

-1 = 3(-1) +2
-1 = -3 +2
-1 = -1

2 = 3(0) + 2
2 = 0 + 2
2 = 2

5 = 3(1) + 2
5 = 3 + 2 
5 = 5

8 = 3(2) +2 
8 = 6 +2
8 = 8

A line with slope 3 passes through the points( 5,2)and (9,y)  Find y

Answers

The ormula of a slope:

m=(y_2-y_1)/(x_2-x_1)

We have the points (5, 2) and (9, y) and the slope m = 3.

Substitute:

(y-2)/(9-5)=3\n\n(y-2)/(4)=3\qquad\text{multiply both sides by 4}\n\ny-2=12\qquad\text{add 2 to both sides}\n\n\boxed{y=14}
