Question

Choose the slope-intercept equation of the line that passes through the point (6, 2) and is perpendicular to y = 3x + 6.
is it
a. y = -1/3x + 4
b. y = 3x + 20
c. y = -3x - 16
d. none of the above

Answer 1

.perpendicular to y = 3x + 6.
perpendicular to a line means, its slope m = -1/m of the line perpendicular to it
m=-1/3 and at point (6, 2) use
y-y1=m(x-x1)
y-2=(-1/3)(x-6)
y-2=-1/3 x + 2
y=-1/3 x +4
