1. pick 2 points
(0,2) (-2,0)
find the slope
m=(y2-y1)/(x2-x1)
m=(0-2)/(-2-0)
m=-2/-2
m=1
use point slope form
y-y1 = m(x-x1)
y-2 = 1 (x-0)
y-2 =x
change to slope intercept
add2 to each side
y = x+2
NOT SURE THE ORDER FOR 2 AND 3 CHECK THE POINTS
2. "v"'s are absolute value equations
vertex is at (-1, -3)
the slope is 1 (it goes over 1 and up (or down) 1
y = m abs (x-h) +k where (h,k) is the vertex
y = abs (x--1) -3
y = abs (x+1) -3
3. "v"'s are absolute value equations
vertex is at (-1, 0)
the slope is 1 (it goes over 1 and up (or down) 1
y = m abs (x-h) +k where (h,k) is the vertex
y = abs (x--1) +0
y = abs (x+1)
