The phone company Blurizon has a monthly cellular plan where a customer pays a flat fee for unlimited voice calls and then a cer
emmainna [20.7K]

Answer:

y=2x+27.

Step-by-step explanation:

We have been given that when a customer uses 14 GB, the monthly cost will be $55. When the customer uses 38 GB, the monthly cost will be $103. We are asked to write an equation in slope-intercept form, where x is the number of GB of data used in a month and y is the total monthly cost of the Blurizon plan.

We have been given two points on line (14,55) and (38,103).  

Let us find slope of line.

m=\frac{103-55}{38-14}

m=\frac{48}{24}

m=2

Now, we will use slope-intercept form of equation.

y=mx+b

55=2(14)+b

55=28+b

55-28=28-28+b

b=27

Therefore, our required equation would be y=2x+27.

-BARSIC- [3]
1) 1ml % 6 marbles = about 0.17ml so the volume per marble is 0.17ml 2) 10-(0.17x4) = 9.32 so that is the original volume 3) then 9.32 + (0.17 x 13) = 11.53ml 4) it is linear because for every marble placed inside the cylinder the volume increases by about 0.17ml the slope means amount of marbles placed vs. volume in cylinder
