A cell phone plan costs $200 to start. Then there is a $50 charge each month. What is the total cost (start up fee and monthly charge) to use the cell phone plan for 1 month?

What is the total cost for x months (answer should be in the form of an expression)?

Is there a proportional relationship between time and the cost of the cell phone plan?
( yes or no)

Step-by-step explanation:

250 1month so 250+(x × 50) x = #of months

250 for one month , 700 for 10 months

Step-by-step explanation:

250 plus 9, 50ds so 50 50 50 50 50 50 50 50 50

The equation of the line is y = -3x - 7

Step-by-step explanation:

To find the equation of the line, we first need the slope. We can get that by using the slope formula.

m(slope) = (y2 - y1)/(x2 - x1)

m = (8 - 2)/(-5 - -3)

m = (8 - 2)/(-5 + 3)

m = 6/-2

m = -3

Now that we have the slope, we use the slope and the given point in point-slope form. Then we solve for y.

y - y1 = m(x - x1)

y - 2 = -3(x + 3)

y - 2 = -3x - 9

y = -3x - 7
