Question

Write and equation of the line containing the specified point and perpendicular to the indicated line.
(4,-2), x=1

Answer 1

The challenge is to determine the slope. What slope is perpendicular to x = 1, which is vertical and has no slope.

Answer 2

if u want to find the slope of a line that is perpendicular to a line that has no slope. the second line would have a slope of 0. right?

Answer 3

Perfect. So the equation will be "y = something". Do you believe?

Answer 4

ok, y=0. is there something that im missing? i need to put it into slope intercept form?

Answer 5

Not y = 0. You missed the point you are supposed to hit.

Forget about slope intercept form. When m = 0, it's a little confusing. Just write it like you did. That IS slope-intercept form for an horizontal line.

Answer 6

(4,-2) x=1,
y would have to be -2 for it to be perpendicular!!! so the equation would be written out as...?

Answer 7

i feel im right there, im just missing something

Answer 8

y = -2
