Question

What is the equation of the line in slope-intercept form? the line perpendicular to

y = 1/3x + 5 through (2, 1)
A. y = -1/3x + 7

B. y = 3x + 7
C. y = 1/3x + 7

D. y = -3x + 7

Answer 1

i know its not A

Answer 2

Line perpendicular to y = 1/3x + 5 m = 1%2F3 through (2, 1)




m = -3

y = -3x + b

1 = -3 * 2 + b Using (x, y) ordered pair (2, 1) to solve for b.

7 = b

y = -3x + 7
