Rachel finished 3/4 of the race in 6 hours. how much time did it take her to finish the entire race?

8 Hours

Step-by-step explanation:

Given: 3/4 part of race completed in 6 hours.

Formula for finding speed is,

Speed=

Now, lets find out the speed at which of the race completed.

Speed=

∴ Speed was to complete of the race.

Lets find out the remaining part of race:

=

∴ part of the race is yet to be completed.

Now, time taken to finish part of race at the same speed of .

Formula for finding time is,

Time=

 Time ()= = 2

∴ Time taken to finish remaining part of race is 2

Now, to find out total time taken to finish entire race is:

Total time=

Total time =

∴ Total time taken to finish entire race is 8

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
