Question

Write an equation of the line that is perpendicular to 2x + 4y = 6 and passes through the point (6,4).

A) y= 2x + 4
B) y= 2x - 8
C) y= -2x + 16
D) y= 1/2x + 4

Answer 1

y = -2x + 16

Explanation:

when two lines are perpendicular, their slopes, (m1)(m2)= -1

then the slope of the given line is 1/2.

(1/2)(m2)= -1 m2= -2

then the straight line formula, y-y1=m2(x-x1)

y-4= -2(x-6)

y = -2x + 16
