A graph with the x-axis ranging from 0 to 4 in increments of 1 and the y-axis ranging from 0 to 4 in increments of 1 shows a line ending with an arrow. The line passes through 3 plotted points: left parenthesis 0 comma 0 right parenthesis; left parenthesis 1 comma 2 right parenthesis; and left parenthesis 2 comma 4 right parenthesis.

A graph with the x-axis ranging from 0 to 6 in increments of 2 and the y-axis ranging from 0 to negative 3 in unit decrements shows a line ending with an arrow. The line begins at the origin and passes through three plotted points. The plotted points include left parenthesis 0 comma 0 right parenthesis; left parenthesis 2 comma negative 1 right parenthesis; and left parenthesis 4 comma negative 2 right parenthesis.

The correct graph to show the relationship between the number of hours using the internet (x) and the cost (y) at a coffee shop, where it costs $2 per hour, is the first graph.

In this graph:

  • The plotted points include (0, 0) which represents 0 hours and $0 cost.
  • (1, 2) represents 1 hour and $2 cost.
  • (2, 4) represents 2 hours and $4 cost.

This shows a linear relationship where the cost is proportional to the number of hours, specifically given by the function \( y = 2x \), where \( y \) is the cost and \( x \) is the number of hours. Therefore, the first graph accurately represents this relationship.
