Point-Slope Form of a Linear Equation

For a given point (x₁ , y₁ ) on a non-vertical line having slope m, the point-slope form is: 

Once an equation is in point-slope form, it can be easily transformed into slope-intercept form.
What could be better, eh?

Sample problem: 
Write a linear equation in slope-intercept form given a line with a slope of ¹/₂ and a point (-4, 6) that is on the line.
