Question 174236
 1. Find the equation of the line that passes through the points (-4,-11)
and(-2,-3).
|x  y   1|
|-4 -11 1| = 0
|-2 -3  1|
x*(-11+3) -y*(-4+2) + 12-22 = 0
-8x +2y = 10
4x - y = -5

2. find the slope of the line containing the given points. P1(3,11), P2(6,17) 
slope, m, = (diff in y)/(diff in x)
m = (17-11)/(6-3)
m = 2
