Answer:
1. y = mx + b
Step-by-step explanation:
y = mx + b
2) to find the y intercept you need to see what cross | ( 8,5)
3) 5 = m(8) = b
4) your slope is negative form the why it pointing
5) in this case your slope is 1/3
6) so now you can do your first step now that you have your (y,x) and slope (your solving for (b)
7)
5 = 1/3 (8) + b
5 = 2.6 + b
5 = 2.6
-2.6
2.4 = b

Step-by-step explanation:
Answer:
5 hours
Step-by-step explanation:
Time taken for trip : t + 1
Time taken for return : t
Avg. speed (trip) : 256 km/h
Avg. speed (return) : 320 km/h
The distances covered on both trips are equal.
⇒ Distance (trip) = Distance (return)
⇒ Speed (trip) × time (trip) = Speed (return) × time (return)
⇒ (256)(t + 1) = (320)(t)
⇒ 256t + 256 = 320t
⇒ 64t = 256
⇒ t = 4 hours
<u>Time (trip)</u> = t + 1 = 4 + 1 = 5 hours
