Slope = (y2 - y1)/(x2 - x1)
Slope = (8 - 0)/(3 - 1)
Slope = 8/2
Slope = 4
Answer
4
T 1 2 3 4
B 3 6 9 12
This is linear relationships B=3*T (it can be also called directly proportional)

Answer:
3.5 hours
Step-by-step explanation:
Distance = 21 miles
Speed * time
Speed * time = distance
Tom speed = 2 mph
Brian = 4 mph
Let time = t
Brian distance + Tom's distance = total distance
4t + 2t = 21
6t = 21
t = 21 / 6
t = 3.5 hours
