Question

for each ordered pair, x,y determine whether it is a solution to the inequality 4x-6y> (greater then/ equal to) -18
(-5,1)
(0,3)
(8,5)
(-9,-2)

Answer 1

Simply substitute the coordinates of each given point into the inequality 4x-6y (greater than or equal to) -18. Is the inequality then true or false? If true, then the point is a solution to the inequality.

Answer 2

well I already have them added up ect and i'm having trouble dealing with if it's true or not

Answer 3

Answer 4

Okay 1 through 5 I got 1)-26(greater then equal too) -18, is yes? and 2 -18>-18 no 3 2>-`18 no 4 -24>-18 yes

Answer 5

Your inequality is
4(x)-6(y) (equal to or greater than) -18.
Supposing we want to test the point (-5,1):
Replace x by -5 and y by 1:
4(-5) - 6(1) (equal to or greater than?) -18
Evaluating: -20-6 (equal to or greater than?) -18
-26 (equal to or greater than?) -18
Answer: No. So the point (-5,1) does NOT satisfy the given inequality.
Test the other points in the same way.

Okay thanks
