I believe it is b and hmu?
The answer is (-6, 5) for K.
In order to find this, we must first note that to find a midpoint we need to take the average of the endpoints. To do this we add them together and then divide by 2. So, using that, we can write a formula and solve for each part of the k coordinates. We'll start with just x values.
(Kx + Lx)/2 = Mx
(Kx + 8)/2 = 1
Kx + 8 = 2
Kx = -6
And now we do the same thing for y values
(Ky + Ly)/2 = My
(Ky + -7)/2 = -1
Ky + -7 = -2
Ky = 5
This gives us the final point of (-6, 5)

Step-by-step explanation:

Answer: There are 14 long pieces she can cut.
Step-by-step explanation:
Since we have given that
Length of yards of ribbon is given by

Length of yards of ribbon pieces need to be cut is given by

Number of yards is given by

Hence, there are 14 long pieces she can cut.
