PLEASE HELP!!!!!

Answer 1

Answer:

B

Step-by-step explanation:

Given

5 - 2x + 7y = 4 ( subtract 5 from both sides )

- 2x + 7y = - 1 ( add 2x to both sides )

7y = 2x - 1 ( divide all terms by 7 )

y = $\frac{2}{7}$ x - $\frac{1}{7}$ → B

Answer 2

Answer:

B. $y=\frac{2}{7}x-\frac{1}{7}$

Step-by-step explanation:

We have been given an equation $5-2x+7y=4$. We are asked to choose the equation that is equivalent to our given equation.  

We will convert our given equation in point-slope form of equation.

$5-2x+2x+7y=4+2x$

$5+7y=4+2x$

$5-5+7y=4-5+2x$

$7y=-1+2x$

$7y=2x-1$

Divide both sides by 7:

$\frac{7y}{7}=\frac{2x}{7}-\frac{1}{7}$

$y=\frac{2}{7}x-\frac{1}{7}$

Therefore, equation $y=\frac{2}{7}x-\frac{1}{7}$ is equivalent to our given equation and option B is the correct choice.
