Answer:
y = 1/2 x + 4
Explanation:
The slope intercept form of an equation is
where m is the slope and b is the y-intercept.
Now in our case the slope m = 1/2; therefore,
Now we just need to find the value of b.
Luckily we are told that the line passes through the point (-6, 1), which means that the above equation must satisfy x = -6 given y = 1.
Putting in x = -6 and y = 1 in the above equation gives
which simplifies to give
adding 3 to both sides gives
Hence, the value of b is 4, and therefore, our equation becomes
which is our answer!
Answer:
It means the Judy's rate to complete the puzzle is
Step-by-step explanation:
If Judy completes a puzzle by herself, it takes her 3 hours.
Working with Sal, it only takes them 2 hours
We have been given the rates of time taken by Judy and Sal to complete a puzzle.
We can see from our given table that Sal's rate is r. We are told that Judy completes a puzzle by herself, it takes her 3 hours. working with Sal, it only takes them 2 hours.
It is given that Judy completes a puzzle by herself, it takes her 3 hours.
so part of puzzle completed by Judy in one hour would be
Therefore, the part of puzzle completed by Judy in one hour is
