Answer:
(6.4, 2.2)
Step-by-step explanation:
(3-1)/(8-4) = 2/4 = 1/2 = m
y = mx + b
1 = 1/2(4) + b
-1 = b
y = 1/2x - 1
perpendicular slope is -2
3 = -2(6) + b
15 = b
y = -2x + 15
2.5 and -0.75
It will go 400 kilometers in 5 hours and 800 kilometers in 10 hours
80*5= 400 (in 5 hours)
80*10=800 (in 10 hours)
