Question

Choose the equation of the line passing through the point (-4, -2) and perpendicular to y = -x + 6.

y = -x + 6

y = x - 6

y = -x - 2

y = x + 2

Answer 1

can you find slope of y= -x+6 first ?

Answer 2

compare it with y=mx+x
m= slope

Answer 3

**y= mx+c

Answer 4

-1

Answer 5

correct.
now product of slopes of perpendicular lines = -1

Answer 6

so, m (-1) = -1
m= slope of required line = ... ?

Answer 7

So it's either A or C

Answer 8

-1

Answer 9

A,C are parallel lines because they have same slope
we need perpendicular line

Answer 10

Woops, my bad.

Answer 11

no...
m (-1) = -1
you got this, right ?

Answer 12

Oh so m needs to be 1

Answer 13

yup!

Answer 14

now use point slope form
know what it is ?

Answer 15

y-y1=m(x-x1) right?

Answer 16

correct

Answer 17

y--2=1(-1--4)

Answer 18

y+4=-1+4

Answer 19

where did x go ?

Answer 20

Dangnabbit

Answer 21

y+4=x+2

Answer 22

lol no :P

Answer 23

OMG. -_-

Answer 24

y +2 = 1 (x+4)

Answer 25

Sigh, y+2=x+4

Answer 26

y=x+2
