Question 110631:  how do i plot the following points on a rectangular coordinate system 
(-3,-2) 
(-1,0) 
(1,2) 
if you were to connect these points with a line, where would the y-intercept be located? give answer in (x,y) form.

You can  put this solution on YOUR website! (-3,-2) 
(-1,0) 
(1,2) 
if you were to connect these points with a line, where would the y-intercept be located? 
--------------- 
Pick a couple of points and find the equation of the line thru them. 
Using (1,2) and (-1,0) 
--------------- 
slope = [2-0]/[1--1] = 2/2 = 1 
------------- 
Form y=mx+b 
Substitute to find "b": 
2 = 1*1+b  
b = 1 
EQUATION: y = x+1 
-------------------------- 
The y-intercept is (0,1) 
======================
