Are the graphs of the lines in the pair parallel? explain. y = 5x + 6 –18x + 3y = –54 no, since the y-intercepts are different. no, since the slopes are different. yes, since the slopes are the same and the y-intercepts are the same. yes, since the slopes are the same and the y-intercepts are different.

No, since the slopes are different.

Step-by-step explanation:

When the lies are parallel then the slopes are equal.

Lets find out slope of each equation and check

For equation of a line , where m is the slope

Slope of first equation = 5

solve for y

Add 18x on both sides

Divide both sides by 3

Slope of second equation = 6

Slope of both equations are not same , so they are not parallel.

No, since the slopes are different.

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

$54.99

step-by-step explanation:

$54.99 includes 500 min. if she does not exceed 500 min then her bill is $54.99
