You go to metropcs and can talk for 60 minutes with the plan for $55, and 90 minutes with a plan that cost $70. write an equation in slope intercept form that represents the total cost y of talking for x number of minutes with metropcs plan

The required equation is

Given that , you go to MetroPCS and can talk for 60 minutes with the plan for $55, and 90 minutes with a plan that cost $70.  

We have to write an equation in slope intercept form that represents the total cost Y of talking for X number of minutes with MetroPCS plan.

We know that, slope intercept form of equation is y = mx + c

Where "m" is the slope of line and "c" is the y-intercept

Now, for 1st case, 60 minutes ⇒ $55

Substitute these values in our equation 55 = 60m + c ⇒ (1)

And for 2nd case 90 minutes ⇒ $70

By substituting those values in equation, 70 = 90m + c ⇒ (2)

Now, subtract (1) from (2)

90m + c = 70

60m + c = 55  

(-)---------------

30m + 0 = 15

Then from eqn 1,

Then our equation is modified as

6 on both sides and twelve on the top and the bottom

step-by-step explanation:

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.
