We can find the midpoint by using the two given coordinates and finding the average between them.
We will find the average between the x coordinates and the y coordinates.
We are given these two coordinates of line segment QR: (-3, 14) and (7, 5). Find the midpoint by finding the average (or mean) between the x coordinates (-3 and 7), and the y coordinates (14 and 5).
Find the average by adding up the two coordinates then dividing the answer you get by 2 (because you added two numbers).
x coordinates average: -3 + 7 = 4, 4/2 = 2; their average is 2
y coordinates average: 14 + 5 = 19, 19/2 = 9.5; their average is 9.5 (or 19/2)
Take the two averages and put them together so your answer is: the coordinate of the midpoint of line segment QR is (2, 19/2).
