Rather than using the absolute value equation to solve for the piecewise function, as the example in the textbook showed, we can write the equations using the .
y=mx+b
We can use the graph of the absolute value function to find the slope of the left piece and the slope of the right piece. Then we use points from the graph, such as
(5,4), to solve for
b. If done correctly, the answer will be the same.
y={mlx+blmrx+br
