Answer:
Step-by-step explanation:
If the vehicle is staying at a constant 30 mph than in 0 hours the vehicle would have reached a distance of 0 miles. In 1 hour the vehicle would have traveled 30 miles. In 2 hours 60 miles, in 3 hours 90 miles, and in 4 hours 120 miles.
Then you would just plot the distance per hour on the x-y axis.
And for the final question on the bottom. As each hour passes the vehicle travels another 30 miles and the slope of the line will continue to grow until the vehicle changes speed.
