A boat travels 4 miles upstream in 4 hours. Going downstream, it can travel 36 miles in the same amount of time. Find the speed of the current and the speed of the boat in still water What is the speed of the current? mph What is the speed of the boat in still water? mph 1​

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

a
