"slope-intercept form" is y = mx + b.
We have a point on this line and we also have the slope of the line. Thus:
3 = 1(2) + b, so b =1 and the equation is y = x + 1.

Let m = slope
Use the point-slope formula.
y - y1 = m(x - x1)
Let y1 = 3
Let x1 = 2
y - 3 = 1(x - 2)
Solve for y.
y - 3 = x - 2
y = x - 2 + 3
y = x + 1
Done!
