Algebra practice question

Answer: 6

On the edge y = −x + 6, x + y = 6, and every other point in the region lies below that edge, so x + y ≤ 6.

Common wrong answers

If you answered 3

3 is the value at the corner (1, 2), the minimum.

If you answered 7

7 would need a point above the line y = −x + 6.

If you answered 8

8 is the sum of the constants, not a value of x + y in the region.
