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)

Help me on this Please!!!
Oliga [24]

Answer:

Function A. <em>nonlinear</em>

Function B. <em>linear</em>

Step-by-step explanation:

Function A is nonlinear because the y values are changing at a nonlinear rate. To get from 0 to 1, the value is increased by 1. However, to get from 1 to 8, it increases by 7, which is different than before.

Function B is linear because the equation models a linear function. You can test this by drawing a table of values similar to Function A:

\begin{center}\begin{tabular}{ c c c c } X & 1 & 2 & 3 \\  Y & 4 & 3 & 2 \\\end{tabular}\end{center}

You can see the y values change at a linear rate of -1 constantly.
