Which of the following is an equation of a line parallel to 2x-y=-1?

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.

black lol

step-by-step explanation:

i can tell you jamal now has 3 cookies xd

tommy has 2.

this made me lol.

hi there!

question 1 answer: p/q can be terminating when q = 5^m * 2^n

question 2 answer: -1 and -1

question 3 answer: -4

question 4 answer: 5/12

hope this : )
