Answer:
what's the question .......
Loretta:
Average driving speed = 55 mph
Time = 4 hours
Distance traveled = 55*4 = 220 miles
Dad:
Average driving speed = 65 mph
Let x = hours driven
Distance traveled = 65x miles
The length of the trip is 610 miles, therefore
65x + 220 = 610
65x = 390
x = 6 hours
Answer: Loretta's dad drove for 6 hours.

Answer:
y=-1/10 x - 41/10
Step-by-step explanation:
slope: y2-y1 / x2-x1 = -5-(-4) / 9-(-1) = -1/10
y= -1/10 x +b, substitute (-1,-4) to solve b
-4=-1/10 (-1) +b
b=-41/10
