Problema Solution
Write an equation of a line given that the line;is horizontal and passes through the point (−5, −6).
Answer provided by our tutors
the line is horizontal if and only if the slope m=0 that is it can be written as
y = 0*x + b, where b the y-intercept
or
y = b
the line goes trough (-5, -6) that is for x = -5 => y = -6 or
-6 = 0*(-5) + b
b = -6
thus the line is
y = -6
