The area of square flake of gold is 
<h3><u>Solution:</u></h3>
Given that width of square flake of gold is 
millimeter
To find : Area of square flake
Since gold flake is in shape of square, we can use area of square formula
<em><u>The formula for area of square is given as:</u></em>
where "s" is the length of one side
Hence , the calculated area of flake is
So we know the lines are parallel.
Thus, the equation should look something like this:
y = 5x + b
Now, we have to solve for b.
Plug x=1 and y=2 into the equation to solve for b
2 = 5 + b
Subtract both sides by 5
-3 = b
b = -3
Plug that value into the equation.
y = 5x - 3
That's your answer.
Have an awesome day! :)
The answer is -11/7 as a mixed number it is( -1 4/7)
