Hi there!
The equation of any line perpendicular to

is

Therefore, in this situation, the formula of the line would be

Given that the line passes through the point (6, 4) we get



Therefore, the equation of the line that is perpendicular to 3x + 9y = 7 and passes through (6, 4) is
I've heard this before, submit the rest and I will attempt to solve.
Answer:
(5 , 3)
Step-by-step explanation:
The midpoint = (3+7)/2 , (9-3)/ 2
= 10/2, 6/2
= (5 , 3)
Is there more to this question or no?
