The Point-Slope form of an equation of the line, is:

Where "m" is the slope and this is a point of the line:

The formula for calculate the slope, is:

In this case, you can set up that:

Substituting values, you get that the slope of the line is:

Knowing the slope and the point (2,6), you can susbtitute values into the equation in Point-Slope form shown at the beginning of the explanation.
Therefore, the answer is:
