53. In the standard (x, y) coordinate plane, the line 2x + y = 5 is reflected across the x-axis. What is the y-intercept of the resulting line?

Answer and Explanation

Your Answer is

Correct Answer is A

Explanation

The analytical formula of the original straight line can be transformed into y=-2x+5, and the intersection with the y-axis is (0,5). So the coordinates of the intersection with the y-axis after symmetry are (0,-5).
