It doesn't seem to be A or C because the slope doesn't look that steep.

After estimating we can see that the slope of B still looks too steep, so I'd say D.

To check, you can see the y-intercept is around 20 and the slope is about 1.

 

You are very welcome!

This won't be precise....but...It appears that the y intercept would be at ≈ 20

 

So.....we only have two equations to consider

 

y = x + 20

or

y = 2x + 20

 

Note that the last data point on the right has a y value of ≈ 65

And the x value associated with this point ≈ 20

And assuming that a line  of best-fit might pass through the second data point from the left 

The coordinates of this point ≈  (2.5, 25)

So....the slope of the line is ≈    [ 65 - 25 ] / [20 - 2.5]   ≈ 2.3

 

Thus....our "equation"   might be    y = 2.3x + 20

 

This is closest   to   y = 2x + 20  ⇒   2nd answer

 

I hope that makes sense, NSS...
