To Find :
The equation of the line that is perpendicular to the line y = 6 and passes through the point (-4,-3)
Solution :
Let, equation of line perpendicular to given line is y = m ....1)
Here, m is a constant.
Putting y = -3 in above equation, we get :
-3 = m
Putting value of m in equation 1), we get :
y = -3
Therefore, correct option is b) x = -3.
