Step-by-step explanation:
When a graph is reflected about the x-axis, their x-intercept(s) are invariant point(s).
For y = 2x + 3, the x-intercept is -3/2.
Also the slope of the line graph when reflected about the x-axis will change from m to -m.
Therefore the new slope is -2.
We have y = -2x + c.
When x = -3/2, y = 0.
=> (0) = -2(-3/2) + c, c = -3.
Hence the answer is y = -2x - 3. (E)
