Question 473266
Find an equation of the line containing the given pair of points 
(-3,-4) and (-8,-1) 
---------------
slope = (-1--4)/(-8--3) = 3/-5 = -3/5
------------------
Form: y = mx + b
---
Substitute for y,x,m and solve for "b":
---
-1 = (-3/5)*-8 + b
-1 = (24/5) + b
-(5/5) = (24/5) + b
b = -(29/5)
--------------------
Equation:
y = (-3/5)x - (29/5)
