Question

Is my explanation right (it’s in the bottom)? Explain if it’s wrong?

Answer 1

Your explanation needs to be reconsidered.

Explanation:

A point is in the solution set only if it satisfies both (or all) inequalities. The point (1, 2) is on the dashed line, so does not satisfy the inequality 4x-y<2. The point (1, 2) is not in the solution set.
