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)
======================
