Determine the type of boundary line and shading for the graph of the inequality -4x - y ≤ -2 My answer is Solid line with shading on the side that includes the origin. Am I right? :)
solid line...yes includes origin? lets check this again...the origin is (0,0) right? so 4x - y ≤ -2 4(0) - 0 ≤ -2 0 ≤ -2 is this statement true?
It's actually the other way round.. Notice the "≤" sign, what does that tell you?
Let's see if the origin is in the shaded region -4x - y ≤ -2 -4(0) - 0 ≤ -2 ... plug in (0,0) 0 ≤ -2 If the last inequality is true, then the origin is in the shaded region If the last inequalityis false, then the origin is NOT in the shaded region
So would it be Solid line with shading on the side that does not include the origin?
that would be correct!
Thank you sooo much! :)
not a problem!
