What is the equation of the graphed line written in standard form? 2x – y = –4 2x – y = 4 y = 2x – 4 y equals StartFraction one-

svp [43]

Answer:

The answer is "2x-y=4"

Step-by-step explanation:

Given:

$2x-y=-4\\2x-y=4\\y=2x-4\\y=\frac{1}{2}(x-4)\\$

The Formula of Slope:

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

by replacing the (2,0) and (0,-4) coordinates in the above formula:

$\to m= \frac{-4-0}{0-2}\\\\ \to m= \frac{-4}{-2}\\\\ \to m= \frac{4}{2}\\\\ \to m= 2\\\\$

if point y intercepting in x then x=0, for this the value of x= 0 and c=-4.

Equation of the line:

$\to y=mx+c$

apply m and c value in the above equation:

$\to y=2x-4\\$

Subtract by 2x on both sides of the equation we get:

$\to y-2x= 2x-4-2x\\\\\to y-2x=-4\\\\\boxed{\boxed{2x-y=4}}\\\\$

san4es73 [151]

Answer:

Michelle purchased 25 audio files in January. The percent increase is 60%

Solution:

Given Data:

Michelle purchases = 25 audio files in January

Again purchased = 40 audio files in February

We need to find the percent increase for the given data.

Step 1:

Use the formula for percent change ,

$=\frac{\text { amount of change }}{\text { original amount. }}$

Step 2:

First we find the amount of change from the question.

Amount of change = 40 – 25

By subtracting, we get 15.

Step 3:

substitute the values in formula we get,

Formula percent change = $\frac{15}{25}$ = 0.6

Percent = 0.6 $\times$ 100 = 60 %.

Result:

Michelle purchased 25 audio files in January. And In February she purchased 40 audio files. Hence the percent increase is 60%.
