Question

Find equation of line through (3, 2); perpendicular to the line y = 4.

Help please

Answer 1

Anything perpendicular to y = 4 will be equations like x = 1, x =2, x = 3, etc

Answer 2

which equation goes through (3,2)?

Answer 3

doesn't say, just says to find an equation that satisfies the given condition

Answer 4

what is the x coordinate of (3,2)

Answer 5

3

Answer 6

all points that are on x = 1 have an x coordinate of 1, so the line x = 1 does NOT go through (3,2)

Answer 7

right so it would be x=3 as answer...and that should go through y=4 no?

Answer 8

x = 3 is the answer since all points on this line have an x coordinate of 3

Answer 9

got you, thanks. I was trying to some how use y=4 with the formula y-y1=m(x-x1) lol

Answer 10

that formula won't work because the slope m is undefined for vertical lines

Answer 11

and x = 3 is a vertical line

Answer 12

ah okay
