Question

y≤-|x-4|. Which is not part of the solution.
A: (1,-4)
B: (2,-2)
C: (3,-1)
D: (1,1)

Answer 1

try to draw the gram or use a graphing calculator to get the pic.

Now that u have a visual determine which is not part of the solution. (1,-4), (2.-2), & (3,-1) are all part of the solution. (1,1) is NOT because the point is not included in the shaded region of your equation(:
Any questions?
