Answer:
m = -1
Step-by-step explanation:
First write the line in slope intercept form y = mx+b where m is the slope and b is the y intercept
x-y = 6
subtract x from each side
-y = -x+6
Multiply each side by -1
y = x-6
The slope is 1
Perpendicular lines have slopes that multiply to -1
m * 1 = -1
m = -1
The slope of the perpendicular line is -1
Answer:
Equation B
Step-by-step explanation:
By going through the equations and comparing them to the question, we can determine the correct equation.
Equation A is the multiplication of the distance they have already hiked by 21.
Equation B is the subtraction of the distance already hiked from the total length of the trail.
Equation C is the same as Equation A, but with a factor of 17.5 instead of 21.
Equation D is the addition of the distance already hiked from the total length of the trail.
Therefore, Equation B is the correct answer.
Given:
Consider the line segment YZ with endpoints Y(-3,-6) and Z(7,4).
To find:
The y-coordinate of the midpoint of line segment YZ.
Solution:
Midpoint formula:

The endpoints of the line segment YZ are Y(-3,-6) and Z(7,4). So, the midpoint of YZ is:



Therefore, the y-coordinate of the midpoint of line segment YZ is -1.
