Question

the equation of a line perpendicular to y-(-)4=2(x-6) is ?
a.y-3=-1/2(x-4)
b.y-3=1/2(x-4)
c.y-3=-2(x-4)
d.y-3=2(x-4)

Answer 1

this is written in point slope form. the slopes must be reciprocals with the opposite sign...

Answer 2

to be perpendicular

Answer 3

what is the reciprocal of 2 or 2/1?

Answer 4

then take the opposite sign.

Answer 5

point slope form is y-y1=m(x-x1)....look for the value where you see the m.

Answer 6

?

Answer 7

umm

Answer 8

im confused

Answer 9

look at your equation and find the number where the m is in my equation.

Answer 10

then flip it and take the opposite sign.

Answer 11

which one is it ?

Answer 12

then look for one of the equations that has that number where the m is.

Answer 13

2 is the value of m in your equation.

Answer 14

write 2 as a fraction by putting it over 1

Answer 15

then flip it and change its sign.
