Although you didn't provide a list of options to choose from, I hope my explanation will help you work this out with ease. :)
This equation is in a form known as "standard form." ax+by=c Standard form is commonly used, however for comparing slopes, there is a more efficient equation to use.
Point-slope form (y=mx+b) allows lines' slopes (y) and y-intercepts (b) to be quickly compared and contrasted. Let's put the equation into this form.
2x-y=-1
-2x -2x
-y = -1 - 2x
*-1 *-1
y= 1 + 2x
Switch pieces around
y= 2x + 1
The slope is 2, the y intercept is 1.
<h2><u>Any line that rises 2 units up for every one unit right and that crosses over the vertical axis at any point other than 1 is your answer.</u></h2>

Answer:
The tax percentage is not needed because the tip was based off the after tax price.
The the total bill was $11
$2.20 divided by 20% = $11
Or
$11 x 20% = $2.20
Step-by-step explanation:
Answer:
x=12
Step-by-step explanation:
The whole angle is 90 degrees right, so if you add the two angles that make up the whole angle, you’ll get 90 degrees. So all you have to do is add the measures and set them equal to 90. That’ll give you a simple equation to solve.
X+42+3x = 90
4x = 90-42
4x = 48
x = 12
I hope this helps you understand, if you don’t, let me know and ill see if i can clear anything up. ;)
