Find the midpoint of CD. C= (7,-4) and D= (-8,-5)

ANTONII [103]

Answer:

( $-\frac{1}{2}$ , $-\frac{9}{2}$ )

Step-by-step explanation:

The equation of a midpoint is as follows:

$(\frac{x_{1} +x_{2}}{2} ,\frac{y_{1} +y_{2}}{2})$

The x-coordinate:

x1 = 7, x2 = -8

7+(-8) = -1

Divide by 2 to get the x-midpoint

-1/2

The y-coordinate

y1 = -4, y2 = -5

-4 + (-5) = -9

Divide by 2 to get the y-midpoint

-9/2

You get:

( $-\frac{1}{2}$ , $-\frac{9}{2}$ )

What is the direct linear variation equation for the relationship?

defon

$\bf \begin{array}{cccccclllll}
\textit{something}&&\textit{varies directly to}&&\textit{something else}\\ \quad \\
\textit{something}&=&{{ \textit{some value}}}&\cdot &\textit{something else}\\ \quad \\
y&=&{{ K}}&\cdot&x
\\ \\
&& y={{ K }}x
\end{array}
\\ \quad \\

\begin{cases}
y=4\\
x=12
\end{cases}\implies y=Kx\implies 4=K\cdot 12$

solve for "K", to see what "K" is, or the "constant of variation",
once you found K, plug it back in y=Kx, and that's the equation
