# How do you write an equation of a line given point (5,0) and slope 0?

A slope of $m = 0$ means this is a horizontal line where for each and every value of $x$ the $y$ value is the same.
Because the $y$ value in the point from the problem, $\left(5 , 0\right)$. is $0$ we know the equation of the line is:
$y = 0$
