Question

A HORIZONTAL line passes through point (-3, -1). Find the equation of this line

Answer 1

horizontal line when slope is 0
so y = mx + b
here m is slope which always with x
and b is y-intercept

Answer 2

like i said horizontal line when slope is 0
so replace m by 0
and use that order pair and replace x and y (x , y )by their vales then solve for b

Answer 3

got it ??
