Which point is NOT a solution of x + 2 y is less than or equal to 8 A. (0, 4) B. (-2, 3) C. (4, 4) D. (6, 0)

hartnn (hartnn):

start plugging in points., like 0,4 x=0, y=4 x+2y <= 8 0+2(4) <=8 8<=8 which is TRUE hence 0,4 is the solution of the inequality so don't mark it repeat this for all the points

OpenStudy (liddoislander):

(-2,3) ? or (6,0) ?

hartnn (hartnn):

those are TRUE, right ? so don't mark them either!

hartnn (hartnn):
