Зу - 2x = 9 what is the rewrited version in y=mx+b

y = x + 3

Step-by-step explanation:

Given

3y - 2x = 9 ( add 2x to both sides )

3y = 2x + 9 ( divide all terms by 3 )

y = x + 3 ← in the form y = mx + b

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
