Question

FAN AND MEDAL

Answer 1

The equation y = 8x + 12, where x is the number of hours and y is the total cost, represents what the surf instructor charges for lessons. Use this information to describe how to draw the line on a graph.

Answer 2

Answer 3

So we basically want to graph this equation?

We start with a table of values which is simple
from 0-4 for example.


X:0,1,2.3,4
Y=8x+12
Y:12,20,28,44

Now make an X,Y graph to graph the points (0,12)(1,20)(3,28)(4,44)

Answer 4

okay

Answer 5

Thank you

Answer 6

No problem, let me know if it makes sense.

Answer 7

So to answer your initial question we can see from the equation

Y = 8x + 12
Where x is the hour
Y and is the cost

Regardless if it's been 30 minutes or 58 minutes the cost is still $12 to start with.
Then 8 dollars for every hour after the first hour.

Answer 8

Thank you

Answer 9

could you possibly help me with another one

Answer 10

Sure

Answer 11

So to find out the y-intercept it's basically asking
what is y when x = 0

So we can tell from the graph that when x = 0 y = 8.

So now instead of charging an initial price of $12
It is now an initial price of $8

Answer 12

so is it 8 and then 12

Answer 13

You seem confused by that question, what is your confusion?

Answer 14

I have to enter a number and then another number

Answer 15

Correct the first number is the value of x
Then the second number is the value of y

The question is asking for the y-intercept so

We can find the Y-Intercept by letting x = 0
And solving for Y

So Y(0) = ?

Answer 16

I understand Thank you

Answer 17

You're welcome, I hope there is no confusion
