Question

Which point is a solution of x + 2y ≤ 4?

Answer 1

if you have a graphing calculator it would help, but like mathmate said if you substitute the numbers in for x and y you should be able to see what the answer would be

Answer 2

Whichever the point is, substitute the x and y values in the inequality and see if the inequality is valid. If it is, the point is a solution, and vice versa.

For example, the point (0,0) is a solution, because 0+2(0)=0 < 4. so the inequality is valid, so (0,0) is a solution.
