The formula of a slope:

m=(y_2-y_1)/(x_2-x_1)

We have the points (0,) and (0, -5). Substitute:

$m=(-5-3)/(0-0)=(-8)/(0)\ \ \ \bbbig{!!!!!}\ \text{division by 0 !!!!!}$

This is the line lying on the y-axis (vertical line x = 0).

Answer:

slope is undefined

Explanation:

Calculate the slope m using the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (0, - 5)

m =
(-5-3)/(0-0) =
(-8)/(0)

Division by 0 is undefined, hence slope is undefined

In fact this is the slope of a vertical line
