Step-by-step explanation:
The reflected point will be equidistant from the point over which it is reflected as the original point and in the same line as the original point and the reflected point.
Find the difference between the x and y values of the given points and add that value (distance) to the reflection point.
x-values: 4-7 = -3 y-values: 0-1 = -1
Add to reflection point x: 4-3 = 1 y: 0 -1 = -1
