Change the equation to slope intercept form and identity the slope and y-intercept -8x+2y=6

gulaghasi [49]

The answer is:

$y=4x+3$

The slope is: 4

The y-intercept is: 3

The explanation is shown below:

1. The slope intercept form of the linear equation is:

$y=mx+b$

Where $m$ is the slope and $b$ is the y-intercept.

2. Therefore, you must solve for y, as following:

$-8x+2y=6\\y=\frac{8x+6}{2}\\y=4x+3$

$m=4\\b=3$

Which letter is the correct answer and why

Julli [10]

Answer:

<h2>Option C</h2>

Step-by-step explanation:

Here,

[Taking 'A' = 'a']

$a \: = \: 4\pi {r}^{2}$

Then for 'r',

$= > 4\pi {r}^{2} = a$

$= > {r}^{2} = \frac{a}{4\pi}$

$= > r = \sqrt{\frac{a}{4\pi} }$

$= > r = \frac{1}{2}\sqrt{ \frac{a}{\pi} }$

Hence,

Option C is correct .
