Y = mx + b
slope(m) = 4/3
(-2,2)...x = -2 and y = 2
now sub and find b, the y int
2 = 4/3(-2) + b
2 = - 8/3 + b
2 + 8/3 = b
6/3 + 8/3 = b
14/3 = b
ur equation is : y = 4/3x + 14/3...or 4x - 3y = -14

2/5
Step-by-step explanation:
2/5=4/10
Answer:
His usual speed is 105 km/hr.
Step-by-step explanation:
Let his usually speed be s km/hr and the distance between the towns be d km. So we have the equations:
s = d/6
s - 15 = d / (6 + 1)
from the first equation:
d = 6s and from the second:
d = 7(s - 15)
Eliminating d we get:
6s = 7(s - 15)
7s - 105 = 6s
s = 105.
