Question 114036
(x[1], y[1]) = (p,q)
-2x + y = 12
y = 2x + 12
This is in the form 
y = mx + b where m is the slope
m = 2
The general point-slope formula is
m = (y - y[1]) / (x - x[1])
2 = (y - q) / (x - p)
2x - 2p = y - q
y = 2x - 2p + q . . (slope = 2, and y-intercept = -2p + q)
2x - y - 2p + q = 0 . . (standard form)
