Write an equation of the line that is perpendicular to y = 1/2x + 3 and passes through the point (10, -5).
A) y = -2x + 15
B) y = 2x - 15
C) y = -2x - 5
D) y = -1/2x

i believe that the answer is

b. y-1=-2(x-4)

hope this !

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
