Question

Jacob has been saving money to spend on souvenirs on the family trip. He plans to spend the same amount each day. The equation y=−15x+60 represents this situation, where x is the number of days and y is his remaining money. What does the number 60 in the equation represent?

Answer 1

`\therefore y=60` Represents Money at 0 days

Explanation:

Given:

The equation
`y=−15x+60` represents this situation,

where x is the number of days and

y is his remaining money.

To Find:

What does the number 60 in the equation represent = ?

Solution:

The given Equation is in the Slope-Intercept Form,i.e

`y=mx+c`

Where,

m = Slope

c = y-intercept

y-intercept: The line which intersect at y-axis. So when the line intersect at y-axis X coordinate is zero.

On comparing we get

c = 60

`\therefore y=60` Represents Money at 0 days
