Question

Find the equation of the straight line passing through the point (3, 5)

which is perpendicular to the line
y = 3x + 2

Answer 1

y = -1/3x + 6

Explanation:

the slope is -1/3 because you find the the reciprocal and switch the sign. To find the y intercept you plug in the points to the equation.

5 = -1/3(3) + b

5 = -1 + b

6 = b
