Question

[4_07]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

are you even typeing?

Answer 2

I was, I accidentally did the wrong thing, sorry!

Answer 3

it's ok just the same thing was with the last one

Answer 4

if it perpendicular, m1m2 = -1
m1=-1
-1/-1=1
so, m2=1

if you then substitute the coordinates (-4,-2) into the two equations with 1 as the gradient you get:

y = x - 6
-2 = -4 - 6
-2=-10
this is incorrect, so it's not this equation.

try it with the second:
y = x + 2
-2 = -4 + 2
-2=-2
this is correct, so y = x + 2 is the correct equation :)

Answer 5

thank you
