Question

in a flash of sheer brilliance, joseph invents a time machine! the machine uses a small nuclear reactor to generate the electricity it needs to travel back in time. the graph shows the proportional relationship between how many years joseph wants to travel back in time, x, and how much electricity (in megawatts) his time machine needs, y. what does the point h represent? josephs time machine needs 25 megawatts of electricity to travel back 10 years. josephs time machine needs 10 megawatts of electricity to travel back 25 years.

Explanation:

Step1: Identify coordinates of H

Point H is at (25, 10) since x (years) is 25 and y (megawatts) is 10.

Step2: Interpret the coordinates

x represents years to travel back, y represents electricity needed. So (25,10) means 25 years back needs 10 megawatts.

Answer:

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