Question

help

Answer 1

Can't help it I love your questions

Answer 2

yes sure really need it

Answer 3

need to know the slope first

Answer 4

Slope can be found by picking 2 points from the graph let's say
(1,25) (2, 35)
Slope = Y2-Y1/X2-X1
Slope = 35 - 25/ 2-1
Slope = 10

Answer 5

The slope represents the change or the rate of growing

Answer 6

what does the slope represent? the monthly cost?

Answer 7

The monthly coast indeed

Answer 8

what does y represent? and y intercept?

Answer 9

y intercept is total cost?

Answer 10

Now to find the y intercept
We have the slope 10
And let's use this point
(1,25)
Y - y1 = m(x - x1)
M is the slope
Y - 25 = 10(x -1)
Y - 25 = 10x -10
Y = 10x + 15
So if we have X =0 We will derive the y intercept which is 15

Answer 11

Y intercept is the coast when the time jn month is 0

Answer 12

yaa thanks the intercept is the total cost

Answer 13

Yes when x= 0 you welcome :)
