"Find the x- and y- intercepts of the graph of each equation." #1. x+y=7 #3. 2x+3y=-6 #5. 5x-4y=-12 "Draw a line with the given intercepts." #7. x-intercept: 4 y-intercept: 5 #9. x-intercept: -6 y-intercept: -8 "Graph each equation using x- and y- intercepts." #11. -3x-6y=12 "For each equation, tell whether its graph is a horizontal or vertical line." #13. y=-2 #15. y=-0.25 "Graph each equation." #17. y=6 #19. y=-7 EVEN IF YOU HELP ME WITH ONE OF EACH FROM EACH SET OF INSTRUCTIONS THAT WOULD BE GREAT. THANKS FOR ALL OF YOU WHO HELP ME! (:
for finding the x and y intercepts just cover the other variable .. for example x+y= 7 cover the x and you get y=7 cover the y and you get x= 7
so its 7?

yup, I believe so
try the same thing with the next two, when you think you have the answer, tell me it and I will tell u if its right
ok?
crap. i just did #2 not #3 i only have to do odd. srry brb
kk- r u using a textbook?
y=-2 x=-3
yup ☺
we do have textbooks but my teacher doesn't let us use it. we only have what frayed diagrams she gives us and our workbook with just problems in it. ): the textbook would be reeeeally useful.
oh..
yeah it sucks
yup
#5. y=-3 x= -2.4 ?
y= 3 but yah
oh yeah i see now #7 how do i do it. and btw i was out sick the whole week she taught all this so i never learned it so you're teaching me right now. (:
Oh.. ok ☺ I feel your pain, I was sick and I had to teach myself

#7. ?
no, you have to plot (0,5) and (4,0) on a graph and then just extend the line with a ruler
oh. i knew that.............
yup ☺
gotta go get a ruler brb
so do 7,9,and 11 because you now know how to do those ☺
kk
ok ill be back in a few then
11. y=-2 x=-4
yep!!
#13, 15 i need help now..
ok the next 2 is hard to explain, but I remember it as "y ski" aka why ski.. if it is only y then it is horizontal, so why would you ski on no slope..
so #13. y=-2 is horizontal? and #15. y=-0.25 is horizontal also?
yup!!
so for 17 and 19 you put a dot on the point it says and then extend the horizontal line with a ruler..
wait, so if it was like x=0 or x= -3/5 it would be vertical? with a slope?
it would be vertical i think for the first one, i'm not sure about the second 1
oh so anything with y is horizontal but x you have to find out?
i'm not 100% sure about x.. I am only just learning this stuff too
sorry
oh lol
yup
so did u graph it?
|dw:1358121722957:dw|
|dw:1358121843564:dw|

so the first one ok
yeah
let me do #19
sorry to take up all your time
