Write and equation of the line using function notation Horiz

Write and equation of the line using function notation. Horizontal; through (0, -5) The equation of the line is f(x)=

Solution

Equation of an horizontal line passing through a point (a, b) is given by y = b.

and iusing function notation, it can be written as f(x) = b

For the horizontal line passing through (0, -5), we have

a = 0, b = -5.

Therefore, the equation of the horizontal line passing through (0, -5), is

f(x) = -5.
