Explanation:
first, we need to identify the gradient of the line y=3x+6.
It is already written in the form y=mx+c, where m is the gradient.
the gradient is 3
for any line that is perpendicular, the gradient is
the gradient of the perpendicular line is
Using the formula
substitute m with the gradient
substitute
simplify to get the equation:
