Which equation represents the function whose data is shown in the table? a. y =2x +1 b. y = x -1 c. y = x+1 d. y = 2x -1

Slope intercept form is:

y = mx + b

"m" is the slope, "b" is the y-intercept(the y value when x = 0)

To find "m" you can use the slope formula:

And plug in 2 points from the table. I will be using the points (1 , 1) and (2, 3)

y = 2x + b

In the table, when x = 0, y is -1. So your y-intercept is -1

y = 2x - 1

Your answer is D
