ANSWER
y = 2/3x + 15
Explanation:
Equation used: y - y1 = m( x - x1 )
y - 9 = 2/3 ( x - -9 )
y - 9 = 2/3x + 6 ( distribution )
y - 9 = 2/3x + 6 ( add 9 to 6 )
y = 2/3x + 15
The variation equation is p = kr^2
<h3>How to determine the variation equation?</h3>
The variables are give as:
Pressure = P
Radius= r
The direct variation from p to the square of r is represented as:
![p\ \alpha\ r^2](https://tex.z-dn.net/?f=p%5C%20%5Calpha%5C%20r%5E2)
Express as an equation
p = kr^2
Where k represents the constant of variation
Hence, the variation equation is p = kr^2
