Answer:

Step-by-step explanation:

y = 2x - 3

Slope of the line perpendicular to this line = -1/2

(4 , 5)

y = mx + b

$y = \dfrac{-1}{2}x+b$

Plugin x = 4 and y = 5 in the above equation,

$5 =\dfrac{-1}{2}*4 + b\\\\5=-2 + b\\\\5 +2 = b\\\\b= 7$

Equation:

$y =\dfrac{-1}{2}x+7$

Step-by-step explanation:

$r = \sqrt{ \frac{ax - p}{q + bx} } \\ {r}^{2} = \frac{ax - p}{q + bx}$

r² (q + bx) = ax - p

qr² + bxr² = ax - p

qr² + p = ax - bxr²

qr² + p = x (a - br²)

$x = \frac{q {r}^{2} + p}{a - b {r}^{2} }$
