(a)
To explain: The way you find the mid-points when end-points are given.
(a)
Answer to Problem 35E
For finding x-coordinates: Add both x-coordinates then divide by 2.
For finding y-coordinates: Add both y-coordinates then divide by 2.
Explanation of Solution
Given information: The end-points are given.
To find the midpoints of given endpoints, you add the x and y-coordinates of the endpoints and then divide by 2.
(b)
To explain: The method of finding the x and y-coordinates of endpoints.
(b)
Answer to Problem 35E
For finding x-coordinates of the endpoints: Multiply the x-coordinates of mid-point by 2, and subtract it from the given x-coordinate of an endpoint.
For finding y-coordinates of the endpoints: Multiply the y-coordinates of mid-point by 2, and subtract it from the given y-coordinate of an endpoint.
Explanation of Solution
Given information: The coordinates of the mid-point and one end-point are given.
To find the endpoint, you should multiply the x and y-coordinates of midpoint by 2. Then subtract it from the given an endpoints.
