There is no attachment to this questions so we do not know which table represents the following. If you re-question, I would be gladly able to do so.

How I can solve this

Answer:

$\boxed{\textrm{B)}\qquad y>4}.$

Step-by-step explanation:

We start by subtracting $1$ from both sides of the second inequality:

$2x > 5 \iff 2x - 1 > 5 - 1 \iff 2x - 1 > 4.$

Therefore, we conclude that:

$y > 2x - 1 > 4 \implies y > 4.$

Therefore, every point that satisfies the system has a $y$ -coordinate greater than $4$ .

Describe and correct the error in writing an equation of the line shown

Rudiy27

Answer:

$y = -\frac{3}{5}x+4$

Step-by-step explanation:

Given:

$(x_1,y_1) = (0,4)$

$(x_2,y_2) = (5,1)$

The attachment completes the question

From the attachment, the slope of the line was calculated as:

$m = \frac{1-4}{0-5}$

This step is inaccurate because the slope of a line is calculated using

$m = \frac{y_2-y_1}{x_2-x_1}$

Which gives

$m = \frac{1-4}{5-0}$

$m = \frac{-3}{5}$

$m = -\frac{3}{5}$

The line equation is then calculated using:

$y -y_1 = m(x - x_1)$

Substitute values for m, x1 and y1

$y - 4 = -\frac{3}{5}(x - 0)$

$y - 4 = -\frac{3}{5}(x)$

Open bracket

$y - 4 = -\frac{3}{5}x$

Make y the subject

$y = -\frac{3}{5}x+4$
