$\bf \textit{area of a circle}\\\\
A=\pi r^2~~ 
\begin{cases}
r=radius\\
-----\\
A=22
\end{cases}\implies 22=\pi r^2\implies \cfrac{22}{\pi }=r^2\implies \sqrt{\cfrac{22}{\pi }}=r$

Given 2 points, write the equation of a line in point-slope form, then convert to slope-interceptform.4) (3, 6) and (8, 6)

ruslelena [56]

First, we have to find the slope

$m=\frac{y2-y1}{x2\text{ - }x1}=\frac{6-6}{8\text{ - }3}=\frac{0}{5}=0$

It is an horizontal line

Point-slope form= = y - 6 = 0 (x - 3)

Slope-intercept = y=mx + b,

let's find b

$\begin{gathered} 6=0(3)+b \\ 6=0+b \\ b=6 \end{gathered}$

y = 0x + 6

y = 6

Answer:

y = -3x + 8

Step-by-step explanation:

You have to find the slope first using the formula $\frac{y_{2}-y_{1} }{x_{2}-x_{1}}$

Insert any two points in the equation (1,5) and (2,2) and you get -3.

Then, you do any x value times the slope (1*-3 = -3) and add so that it equals the corresponding y value (8).

This makes it y = -3x + 8.
