Which point is not in the solution set of 3x+2y< 12? a (1,4) b (2,3) c (3,1) d(4,-1)

Test each one out! Coordinates are written in (x, y) so just substitute each one

A) 3(1)+2(4) = 11
B) 3(2)+2(3) = 12
C) 3(3)+2(1) = 11
D) 3(4)+2(-1) = 10

Out of all these answers B has a value less than 12 so the answer is:

B (2,3)

B. Would be the answer all others are valid .

Yeah she/ he needs look how long that is man

Tha answers are c. 2 and d. 7.5 ; )
