Answer:

Step-by-step explanation:

You would first need to find the slope.  The Slope formula is m = (y2 - y1)/(x2 - x1).  In your problem, (1, 2) could be (x1, y1) and (2, 5) could be (x2, y2).  Substitute those values into the Slope formula to find m which is your slope.

The point-slope form of a line is y - y1 = m(x - x1).  You already have (x1, y1) to substitute in so do that and also substitute in your m.
