Question

What is the equation of the line represented by the table of values?

A. y = x + 2
B. x = y − 2
C. y= x − 2
D. x = y + 2

Answer 1

Answer: (C) y= x − 2

Explanation:

y=x-2 is the choice that satisfies all the points in the table. This can be verified case by case:

y=x-2

(-3,-5): -5 = -3 -3

(-1,-3): -3 = -1 - 2

(1,-1): -1 = 1 - 2

(3, 1): 1 = x - 2

(5,3): 3 = 5 - 3
