Answer:
Your answer would be I= (2,-1) J= (2,-3) and K= (5,-2)
Step-by-step explanation:
By reversing the coordinates across the x-axis, you will reverse the y coordinate (ex. 4,1 will become 4,-1). If you reverse the coordinates across the y-axis, you will reverse the x coordinate.
Distance = rate x time
Distance = 221 miles
Rate = 68 mph
221 miles = 68 mph x time
221 miles/68 mph = time
3.25 hours = time
The answer is <u><em>0.76075</em></u>!
