Question

Which correctly describes how the graph of the inequality 4x - 2y > 20 is shaded?

Above the solid line

Below the solid line

Above the dashed line

Below the dashed line

Answer 1

@kidrah69 , @Michele_Laino

Answer 2

Shade above the line for a "greater than" (y> or y≥)
or below the line for a "less than" (y< or y≤).

Answer 3

Would it be above the dashed line?

Answer 4

< or > = dotted lines
≤ or the other one = solid

Answer 5

4x - 2y > 20
-2y > -4x + 20 -- when dividing by a negative, the inequality sign changes
y < 1/2x - 10

there will be a dashed line because there is no equal sign in the problem.
It will be shaded above the line because of the greater sign

Answer 6

So it's above the dashed line?

Answer 7

yes

Answer 8

It's not correct it say's.

Answer 9

you have to put the problem in y = mx + b form.....basically, solving for y....and you go by the inequality sign you get there.....and sometimes the inequality sign will change...

Answer 10

oh, but above the dashed line wasn't right though.

Answer 11

oh crap...I am so sorry...it is a dashed line...but shaded below
y < 1/2x - 10......thats a less then sign

Answer 12

Yes, I believe that is the correct one because of the inequality symbol, thanks for your help1

Answer 13

sorry about the screw up

Answer 14

It's fine :)
