What is the equation of the function shown in the table?

input x -2 -1 0 1 2

output y -3 -1 1 3 5

a) y = -x - 1

b) y = 2x + 1

c) y = 2x - 2

d) y = -2x + 1

B

Step-by-step explanation:

In the table below, the function increases by 2 from each output.

Input x-2-1012

Output y-3-1135

This means it has a constant rate of change or slope. This is a linear function. All linear functions have the form y = mx + b where m is the slope and b is the y-intercept. The y-intercept is the y value when x = 0. Here b = 1. Substitute  m = 2 and b = 1 into y=mx+b to write the equation.

y = 2x + 1
