Question 243697
1. Find the slope of the line containing the given pair of points. If the slope is undefined state so (5,3) and (8,-4)
---
slope = (-4-3)/(8-5) = -7/3
----------------------------------- 
2. Select the line that has the given slope and y intercept. 
slope -1/5, y intercept (0,-2)
You have the slope and intercept.  Put them into the form:
y = mx + b where m is the slope and b is the intercept.
Equation:
y = (-1/5)x-2
