Answer:

$8.49\ units$

Step-by-step explanation:

we know that

The Pythagorean Theorem states that in a right triangle

$c^2=a^2+b^2$

where

c is the greater side (the hypotenuse)

a and b are the legs

In this problem

Let

c=AB ---> distance from point A to point B

a ---> the difference of the x-coordinates both points

b ---> the difference of the y-coordinates both points

$a=1-(-5)=6\ units\\b=6-0=6\ units$

substitute

$AB^2=6^2+6^2$

$AB^2=72$

$AB=\sqrt{72}\ units$

$AB=8.49\ units$

What is the slope of a line that is perpendicular to the line y = x + 4? The slope of the line is ______?

serg [7]

Slopes of perpendicular lines are opposite reciprocals of each other. The slope of the given equation (which is in slope-intercept form) is 1, the invisible coefficient of x. The opposite reciprocal of 1 is -1, thus the slope of a line perpendicular to the line y = x + 4 is -1.

Hope this helps.
