# Slope-intercept form
y = mx + b
with m stands for the slope, b stands for the y-intercept
# Given from the question
m = -6
y-intercept = 3 ((0,3) means that the y-intercept is equal to 3)
# Solution: substitute the information to the slope-intercept form
y = mx + b
y = -6x + 3
The equation of the line is y = -6x + 3
Step-by-step explanation:
The river is 1000 m wide, and the boat moves at 3 m/s, so the time it takes to cross the river is:
t = (1000 m) / (3 m/s)
t = 333.3 s
The river flows at 2 m/s, so by the time he reaches the other bank, he drifts downstream a distance of:
d = (2 m/s) (333.3 s)
d = 666.7 m
