Question 524148
Express the equation in slope-intercept form.
Containing the points P=(-2,1) and Q=(-1,-1) 
---------------------
slope = (-1-1)/(-1--2) = -2/1 = -2
------------------------
Form y = mx +b
---
You know m = -2 and y = 1 when x = -2.
Solve for "b";
1 = -2*-2 + b
b = -3
-----
Equation:
y = -2x-3
