Answer:
Step-by-step explanation:
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)
Answer:
Step-by-step explanation:
6. 78-2(3+16) /4
(78-2x19)/4
( 78 -38)/4
40/4=10
7.
(66/11)3 -6*8
6x6x6 -48
216-48=168
8.
10/7+2(8-11/2)
10/7+2(8-5.5)
10/7+2*2.5
10/7+5
10/7 + 35/7
45/7 =
Y = 3x - 14. use expression y = mx+b where m is slope (use formula for finding slope between any two coordinates) and b is the y intercept, which u can find by using y = mx+b as well and plugging in values
