Algebra - Linear functions

The figure presents the graph of a line in the coordinate plane. The horizontal m-axis is labeled “Time, in minutes,” and the numbers 0 through 7 are indicated. The vertical d-axis is labeled “Distance traveled, in feet,” and the numbers 0 through 7 are indicated. The line passes through the points with coordinates 1 comma 2 and 3 comma 6.

The graph above shows the distance traveled d, in feet, by a product on a conveyor belt m minutes after the product is placed on the belt. Which of the following equations correctly relates d and m ?
