Question

Which of the function rules below would result in the following graph?

Answer 1

A.

Explanation:

We can see that for every two units that a point on the line moves horizontally, it moves one vertically. Using the rise/run formula, we can see that the slope (or the x multiplier) is 1/2, or 0.5. This narrows our answers to A or B.

Now, notice that the line starts at one above the point (0, 0). This means that the number being added to x would be 1. (If the line started below the point (0, 0), the number would be negative.)
