Question

what does the point h represent?
josephs time machine needs 10 megawatts of electricity to travel back 25 years
josephs time machine needs 25 megawatts of electricity to travel back 10 years.

Explanation:

To determine what point \( H \) represents, we analyze the graph's axes. The \( x \)-axis is labeled "Years" (representing time travel years) and the \( y \)-axis is labeled "Megawatts" (electricity needed). Point \( H \) has coordinates \( (25, 10) \), meaning at \( x = 25 \) (25 years travel) and \( y = 10 \) (10 megawatts). The first option matches this: "Joseph’s time machine needs 10 megawatts of electricity to travel back 25 years." The second option swaps the values (25 megawatts for 10 years) and is incorrect.

Answer:

Joseph’s time machine needs 10 megawatts of electricity to travel back 25 years.
