Question

Which point is a solution to the following system of inequalities?
x – 2y > 10
3x + 4y < 10

a.) (1, 10)
b.) (2, –3)
c.) (4, –4)
d.) (–2, –5)

Answer 1

Plug in to test... the point must evaluate to a true statement for BOTH inequalities. answer a is definitely not a solution.

Answer 2

yes, the final step in any solution is the "double check". That is all this amounts to is double checking which options fit

Answer 3

@amistre64 ... a shortcoming of multiple choice assessment to be sure!
