To do this, you got to square 256.
The square root of 256 is 16.
Therefore, there are 16 small squares on each edge of the mosaic.
Kinda proof:

o o o o O
o o o o O
o o o o O
o o o o O
25 squares. Square root is 5. 5 along each edge. My work shares same concept.
Extremely unnecessary proof:

o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O

There are 256 squares, and you can count 16 on each edge. this shows 16 times 16, or 16 squared, which is 256.
Add the two and you should get 2 and 7/16
Answer:

Step-by-step explanation:
step 1
Find the slope
The formula to calculate the slope between two points is equal to

we have
the points (−1,12) and (1,2)
substitute



step 2
we know that
The equation of the line in slope intercept form is equl to

where
m is the slope
b is the y-intercept
we have


substitute in the linear equation and solve for b


therefore

About 2 minutes and 33 seconds?
