<h2>Answer: y - 2 = ¹/₃ (x - 9)</h2>
<h3>Step-by-step explanation:</h3>
<u>Find the slope of the perpendicular line</u>
When two lines are perpendicular, the product of their slopes is -1. This means that the slopes are negative-reciprocals of each other.
⇒ if the slope of this line = -3
then the slope of the perpendicular line (m) = ¹/₃
<u>Determine the equation </u>
We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:
⇒ y - 2 = ¹/₃ (x - 9)
<h3> ∴ the perpendicular line is y - 2 = ¹/₃ (x - 9)</h3>
