Math Linear function help?

How do you write an equation of a line in slope intercept form if two points are given? Ex. Say you were given the points (0,6) and (4,3)? What would you do?

The slope of the line is
m = (y2y1)/(x2x1)
=(36)/(40) = 3/4
When x = 0, y = 6, so the yintercept is 6.
y = (3/4)x + 6 is the equation you want.
