Question

Y=9x+3>> is this true, false, or open??

Answer 1

this is redundant, it can be rewritten as y=3x+1. to better understand this we can easily graph this line in the form y=mx+b.

Answer 2

First you have to know the value of either x or y. If x is 2, and y is 20, it would be false.

But if x is 2 and y is 21, it would be true.

So, the equation is open!
