Answer:
I think the answer would be -1/2 or D.
Step-by-step explanation:
Use this formula for calculating slope : y2-y1 / x2 - x1
1. label the pairs, 1 and 2
(-6, 1) - ( x1, y1 ) or (4,-4) - (x1, y1)
(4,-4) - ( x2, y2) (-6,1) - (x2, y2)
(the order does not matter)
2. Than plug in your numbers
y2-y1 / x2 -x1 y2-y1 / x2 -x1
-4 - 1 / 4 - (-6) or 1 - (-4) / -6 - 4
= -5/10 or -1/2 = - 5/-10 or -1/2
im only in eight grade so i did my best explaining , and this hope it helps :)
We can write this in math as x+y+z=104, x=y-6, and z=3y
Because we already know what x and z are in terms of y, we can substitute our values for x and z into the first equation. This now looks like (y-6) + y + (3y) = 104. Now we can simplify our equation to find our value for y.
y-6 + y + 3y = 104 simplifies to 5y - 6 = 104, then 5y=110, and finally y=22.
Now that we know our value for y we can find our values for x and z by substituting our value for y into the other two equations.
The second equation x = y-6 can be simplified as x = 22 - 6 and further simplified as x = 16.
The third equation z = 3y can be written as z = 3(22) or z = 66.
Our three numbers are 16, 22, and 66. Hope this helps you!
