Cot(x)=cos(θ)/sin(θ) and sec(θ)=1/cos(θ)

Therefore: cot(θ)*sec(θ)= (cos(θ)/sin(θ))*(1/cos(θ))= 1/sin(θ)= csc(θ)

Line is Passing through the Points (-3 , -1) and (-5 , 4)

Slope of a Line Passing through two points (x₁ , y₁) and (x₂ , y₂) is given by :

$\heartsuit\;Slope(m) = \frac{y_1 - y_2}{x_1 - x_2}$

here x₁ = -3 and x₂ = -5 and y₁ = -1 and y₂ = 4

$\heartsuit\;Slope(m) = \frac{-1 - 4}{-3 + 5} = \frac{-5}{2}$

Answer:

Step-by-step explanation:

swap y and x in the function. that is

$x = f(y)$

we get x=4y+5

Solve for y

(x-5)/4=y

$f ^{ - 1}(x) = \frac{1}{4} (x - 5)$
