(y-2)=2(x-1)(y−2)=2(x−1)

Explanation:

When given a point (x_1,y_1)(x1,y1) and the slope mm
you can plug it into the point slope form of
(y-y_1)=m(x-x_1)(y−y1)=m(x−x1) to get your equation.

So, given your point of (1,2)(1,2) and a slope of m=2m=2
we can plug in x_1=1x1=1, y_1=2y1=2, and m=2m=2
into (y-y_1)=m(x-x_1)(y−y1)=m(x−x1)

to get:
(y-2)=2(x-1)(y−2)=2(x−1)
