Question

What is the equation of the line that passes through the point (3,−3) and has a slope of 0?

Answer 1

f(x) = -3

Explanation:

it will be a constant function because if the slope = 0, the y value is not changing

so the equation of the line, f(x) = ax+b, will be f(x) = 0x+b

f(x) = b, b is the y value here

Answer 2

x = 3

Explanation:

A line with a slope of 0 is a horizontal line parallel to the x- axis with equation

x = c

where c is the value of the x- coordinates the line passes through.

the line passes through (3, - 3 ) with x- coordinate 3 , then

x = 3 ← equation of line
