Question 416465
What does "P" stand for when your reading a graphing equations? 
EX: P(3,1); slope 2
------------------------ 
Between quadrants 1 and 4 is 5y between quadrant 2 and 3 is 5x. Center of all quadrents is (0,0).
----
The "P" means point.
You are told the line goes thru point (3,1) and the slope is 2
---
Form: y = mx + b
Substitute and solve for "b":
1 = 2*3 + b
b = -5
---
Equation: y = 2x-5
