Thread: Equation of absolute an absolute value function

Hello forum, Vaironxxrd here.
I missed a day school and some content in Algebra 2.

I'm required to make an equation using a given vertex and a given point.

Vertex = (0,1)
Crosses through(1,-2)

I would say the equation is y=2|x-0|+1
Is this wrong?

1. If you plug in the coordinates of the given point you'll get:



This is true only if you are a banker.

2. Start with



plug in the coordinates and solve for a.
