In the graph of the inequality x - 2y ≥ 4, which is a value for x on the boundary line and the x-axis

Question

A. 4
B. -2
C. 2
D. -4

Answer 1

To find a value for x on the boundary line, we can set y to 0 and solve for x.

Plugging in y = 0 into the inequality x - 2y ≥ 4, we have:
x - 2(0) ≥ 4
x ≥ 4

The value for x on the boundary line is x = 4.

To find a value for x on the x-axis, we can set y to 0 and solve for x.

Plugging in y = 0 into the equation x - 2y ≥ 4, we have:
x - 2(0) ≥ 4
x ≥ 4

The value for x on the x-axis is also x = 4.

Therefore, the correct answer is A. 4.
