Help me plz I don't understand this

D.

Step-by-step explanation:

A proportional relationship is represented by the formula .

m = the slope, which is  .

b = the y-intercept, the point where the line crosses the y-axis. We actually don't have to worry about the part of the formula because , so it can be left out.

To find the slope, use . Subtract the smaller y value (2) from the larger y value (6).

(6 - 2 = 4)

Then subtract the smaller x value (1) from the larger x value (3).

(3 -  1 = 2)

So it looks something like this now:

, which equals

Then you divide the top part of the fraction (4) by the bottom part. (2).

= 2. The slope (m) is 2.

So the final equation is .
