Question

Write the equation of the line perpendicular to y =5/6x+1/6 that passes through the point (-9,3)

Answer 1

y = -6/5x + 13 4/5

Explanation:

Step 1: Perpendicular slope

We need to find the perpendicular slope, or the opposite reciprocal.

This means we change the sign (positive, negative)and flip the numbers

Perpendicular sope to 5/6x = -5/6x = -6/5x

Step 2: Plug in coordinates

Now we plug in the coordinates for y = -6/5x + b

3 = -6/5(9) + b

3 = -10.8 + b

b = 13.8 or 13 4/5
