Answer:
106.63%.
Step-by-step explanation:
We have been given that at the end of 2005, this price was $513. At the end of 2015, it was $1060.
To find the percentage of the price per ounce of gold increase we will use % increase formula.
Let us substitute our given values in above formula.



Therefore, the price of per ounce of gold increased by 106.63%.
y = m x + b is a linear equation.
This equation is in the slope - intercept form, where m is the slope and b is y - intercept.
For example: y = 2 x + 5
In this equation: m = 2 ( the slope ) and b = 5 ( the line intercepts y-axis at the point ( 0, 5 ) ).

Answer:
y = 2/5x
Step-by-step explanation:
Perpendicular lines are lines which have negative reciprocal slopes of each other.
The line y = -5/2 x + 2 has slope -5/2. Therefore its perpendicular slope will be 2/5.
The equation can cross anywhere on the y-axis for its y-intercept since no specific point is given. Here I chose (0,0).
y = 2/5x
