Draw a vertical line through the given point. What other points are on this line?
OpenStudy (gabebae):
y= 1
x= -9
OpenStudy (anonymous):
another point would be 0,1?
OpenStudy (anonymous):
I still don't understand how I would find the correct answer?
they are asking for:
Vertical line: ______
Horizontal line: _____
jimthompson5910 (jim_thompson5910):
vertical means straight up and down

jimthompson5910 (jim_thompson5910):
what point is directly above (-9,1) ?
OpenStudy (anonymous):
Wow sorry i thought you meant horizontal
jimthompson5910 (jim_thompson5910):
that's fine since that's also being asked
OpenStudy (anonymous):
-9,2?
jimthompson5910 (jim_thompson5910):
use parenthesis (-9,2)
but yes, correct
what else is on this vertical line?

(-9,3)
OpenStudy (anonymous):
also, -9,-1
jimthompson5910 (jim_thompson5910):
what do all of these points have in common?
OpenStudy (anonymous):
-9
jimthompson5910 (jim_thompson5910):
more specifically, the x coordinate is -9

jimthompson5910 (jim_thompson5910):
so we simply say the equation is x = -9
jimthompson5910 (jim_thompson5910):
x = -9 is the equation where the x coordinate is stuck to being -9
EVERY point on this line has an x coordinate of -9
y can be anything you want
OpenStudy (anonymous):
Okay that makes sense x=-9 for the vertical line?
jimthompson5910 (jim_thompson5910):
yes
OpenStudy (anonymous):
So for the horizontal line wouldn't y=1? because of the same reasons above

OpenStudy (anonymous):
in that case x could be whatever
jimthompson5910 (jim_thompson5910):
you nailed it
OpenStudy (anonymous):
THANK YOUUUUU

you're welcome
