Question

Anyone?
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

the line is perpendicular to y = -x + 6 so its slope will be 1....
all bcoz if two lines are perpendicular then product of their slope is -1

Answer 2

More generically, the slope of a line perpendicular to another line will be the negative reciprocal. For example: If the slope of one line is 8, the line perpendicular to it will have a slope of -1/8.

Now that we know that the slope of the line perpendicular to y = -x + 6 is 1, we can solve for the y-intercept by plugging in the the point (-4, -2) into y = x +b and solving for b.

Answer 3

So, C?

Answer 4

Or A

Answer 5

@dcabeche

Answer 6

x+b would be 6 after you plug it in

Answer 7

Am I right?

Answer 8

The equation that you are solving is \[-2 = -4 + b\] \[b = 2\] Therefore, the equation of our line is \[y = x + 2\]

Answer 9

Oh, okay. Gotcha. Thanks. :)
