Find an equation of the line passing through the point ( 6 , − 4 ) (6,-4) and perpendicular to 9 x − 3 y = 9 9x-3y=9 . write your answer in slope-intercept form.

Step-by-step explanation:

We are given;

We are required to determine the equation a line passing through a point (6, -4) and perpendicular to the given line;

y = 3x -3

But; m₁ × m₂ = -1 (For perpendicular lines)

Therefore;

m₂ = -1 ÷ 3

    = -1/3

Therefore, the slope of the line in question is -1/3 and the line passes through (6, -4).

To get its equation, we get another point (x, y)

Then;

Thus;

In the form of slope-intercept, the equation will be;

Thus, the equation of the line is;
