Alimited of a number is the product of that number and a natural number

Natural Numbers. {1, 2, 3, 4… ... (natural numbers and zero), and they also include negative ... terminate, having a limited number of digits after the decimal point ...

Step-by-step explanation:

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
