Grace is comparing cell phone plans. a prepaid phone plan costs $0.20 per minute and has no monthly fee. a contracted phone plan costs $50 per month and $0.02 per minute. how will the graphs of the monthy costs of the two cell phone plans compare where x represents minutes purchased in a month?

the prepaid phone plan will have a steeper line and lower y-intercept.
the contracted phone plan will have the same steepness and a higher y-intercept.
the prepaid phone plan will have a less steep line and the same y-intercept.
the contracted phone plan will have a steeper line and same y-intercept.

 The prepaid phone plan will have a steeper line and lower y-intercept.

Step-by-step explanation:

Let x represents the number of minutes while y represents total cost of one month,

According to the question, A prepaid phone plan costs $0.20 per minute and has no monthly fee.

Thus, equation of line which shows it,

y = 0.20x  ------- (1)

And,  A contracted phone plan costs $50 per month and $0.02 per minute.

Thus, equation of line which shows it,

y = 50+0.020x -------(2)

Since, After plotting both lines we come to know that the slope of line 1) is greater than 2) therefore line 1) is steeper than 2).

Also, The y-intercept of 1) is (0,0) and y-intercept of 2) is (0,50)

Therefore Line 1) has the lower y-intercept than line 2).

Thus, Option One is correct.

A. The prepaid phone plan will have a steeper line and lower y-intercept.

Step-by-step explanation:

did it on edge 2020

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
