F (x) = 2x + 3; find f (–1)" (pronounced as "f-of-x equals 2x plus three; find f-of-negative-one"). In either notation, you do exactly the same thing: you plug –1 in for x, multiply by the 2, and then add in the 3, simplifying to get a final value of +1

Which correctly describes how the graph of the inequality 6y-3x>9 is shaded
rewona [7]
We already know that it will be a dashed line because there is no equal sign in the problem.

6y - 3x > 9
6y > 3x + 9
y > 3/6x + 9/6
y > 1/2x + 3/2

<span>And greater then means shaded above the line.

I hope this helped! :)
