Question

At breakfast, a restaurant charges $2 for the first cup of orange juice and then $1 for each refill. Which graph represents this situation?

Answer 1

y = x + 2

the graph with the y int (where the line crosses the y axis) at (0,2).....it will have a slope of 1.....and an x int (where the line crosses the x axis) at (-2,0)

Answer 2

Answer: We can plot the graph with help of below explanation.

Explanation:

Here, At breakfast, a restaurant charges $2 for the first cup of orange juice and then $1 for each refill.

Let x represents number of refill and y represents total charge for x refill then the function, we get,

y= 2 + x

Since the x-intercept of the given line is (-2,0)

And y-intercept is (0,2)

initially x=0, y=2

In first refill x =1 y =3

In second refill x=2 y= 4

In third refill x= 3 , y=5

Thus the points of the above line are (0,2), (1,3), (2,4) and (3,5).

Therefore, with help of the above information we can plot the graph of the above function.
