Question

How do I graph x-3y<6 and 2x+y>1.5

Answer 1

Make:
< and >
To equal signs.
Put the equations into \(y=mx+b\) form.
Then if the original equation has:
> (Shade up and dotted line).
< (Shade down and dotted line).

Remember if you divide by a negative the sign flips!

Answer 2

How do I find y=mx+b?

Answer 3

isolate y to get y=mx+b
example of a T chart to plot some points for the first one.
