Against the wind:
distance = 3400 km
time = 5 hr.
rate = d/t = 3400/5 = 680 km/hr
With the wind:
distance = 3400 km
time = 4 hr
rate = d/t = 3400/4 = 850 km/hr
Equations:
plane speed - wind speed = 680 km/hr
plane speed + wind speed = 850 km/hr
2(plane speed) = 1530
plane speed = 765 km/hr
Substitute and solve for "wind speed":
765 + wind speed = 850
wind speed = 85 km/hr

Answer:
y = x - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = and c = - 4 , then
y = x - 4 ← equation of line
