find the area enclosed by these sets of three lines.
a) y=0, y=1x+1 and y=-x+10 2
Not clear.
==================
b) y = 2, x - y = 5 and x + y = 1
You can find the 3 side lengths, then use Heron's Law.
Might be easier to find the 3 vertices, then use area = b*h/2

It's a lot of arithmetic. I don't need any practice and I won't learn anything by doing it.
You might.
