linear equation

Question

Find an equation of the line that satisfies the given conditions.

Through (4, 5) and (6, 5)

Answer 1

y=5 is the equation of the line through the two points (4,5) and (6,5)

if the y coordinates of the two points are the same, then the line through them is a flat horizontal line with y= whatever those 2 same y coordinates are, in this problem that's 5
