Common means similar/alike in this case. to have the highest common factor, you need it to be common with the two numbers. both numbers are negative, so the highest common factor is also negative.
remember, you aren't multiplying/dividing to get a product or quotient; you'r simply looking for a number.

To find reciprocal, flip the top and the bottom.
So
would be
.
Multiply like normal.
The point (6, 6) is the mid-point of A and B. Then the coordinate of the point B is (7, 5).
<h3>What is coordinate geometry?</h3>
Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.
Point A (5, 7) is reflected over the point (6, 6) and its image is point B. Then the point (6, 6) is the mid-point of the A and B. Then the coordinate of the point B will be
