The answer is going to be 4.5%

Based on this question, we know that Diego measured the length of a pen which were to be 22cm so that we would get the actual length of the pen that is 23cm.

So what we need to do is do the percentage//which is decreasing

(22-22)/22x100

=1/22x100

=4.5%, therefore the percent error for Diego’s measurement is 4.5% because what we did was find the percentage decrease by multiplying 100 by 22 minus 22 over 22.

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}}\\\\
