Question

Help? *Fan and Medal* What is the y-intercept for this table? And what could this represent in real-world context?

Answer 1

The y intercept of a graph is when x=0, thus we can apply this to a table by have x = 0

Answer 2

linear tables produce constant change.. find the change in y

Answer 3

the change is 60.

Answer 4

Could you find the equation in the form y=mx+b to describe the function

Answer 5

y=60x + 120?? Was that correct?

Answer 6

Plug in a value of x, do you get the corresponding y value

Answer 7

Explain further?

Answer 8

let x = # of hrs || y = total cost... if x=2 hrs, the total cost(y) should be $120 according to the table. Using your equation y=60x + 120, when x = 2, y =140.

Answer 9

We need a equation that satisfies ALL values of x and the corresponding y values..

Answer 10

You said earlier that the constant change is 60, your correct... now lets multiply that by x.. giving us 60x... Test Our Values: When x =2 || y =120.. Hey that works ! Why don't you try
