Question

Write the equation of the line which passes through (2, 1) and is perpendicular to x = –2. (1 point)

Answer 1

What kind of line is x=-2?

Answer 2

intercept.I think.

Answer 3

Its a vertical line =p

so, that means a line that is perpendicular to it must be horizontal right?

Answer 4

yes

Answer 5

Alright. the equation of a horizontal line is just y=any y coordinate on the line

so in this case y=1

Answer 6

so it can be y=0 or not.

Answer 7

Not sure i understand what you mean.

the equation of the line is y=1

Answer 8

oh i got it.
But how do i find the slope when x=-2

Answer 9

The slope of the line x=-2 is undefined as it is a vertical line

Answer 10

so that one is impossible right.

Answer 11

what do you mean?

Answer 12

because you said x=-2 is undefined so it's impossible to find the slope
y=mx+b so where do i find the m and b.
