(6,7) should be the answer
It means putting X at the front. So you'd express the equation as x = ay + b
Little tip....notice how ur y coordinates are the same....this means that u have a horizontal line which is represented by y = a number...with that number being the y coordinate of ur points.
So ur equation is : y = -3 <===
** if ur x's would have been the same, it would be a vertical line represented by x = a number...with that number being the x coordinates of ur points...but thats only if ur x coordinates were the same
Answer: The shortest living man at that time had the height that was more extreme.
Step-by-step explanation:
We will z scores to solve this exercise. The formula we need is:

Where
is the raw score,
is the mean and
is the standard deviation.
We know at that time heights of men had a mean of 170.53 centimeters and a standard deviation of 5.91 centimeters, then:

Knowing that the tallest living man at that time had a height of 230 centimeters, we get:

And knowing that the shortest living man at that time had a height of 91.3 centimeters, we get:

Based on this, we can conclude that the shortest living man at that time had the height that was more extreme.
True because there is no number that 7 is divisible by since it's a prime number
