Question

Help me please!!!!!!



x-4y=-4
3x+10y=30
what quadrant would this be in?

Answer 1

if x-4 = -4, then you want to find what x is, right?
so, to isolate "x", what should you do?

Answer 2

you add it to both sides?

Answer 3

correct! =)
you can plot x as zero on the graph, now.
you remember where 0 is on the number line =)

Answer 4

now for y...
if x = 0, how should we solve the equation for y? Remember that we want to isolate y

Answer 5

you divide y?

Answer 6

correct!
3(0) + 10y = 30
10y = 30
divide "10" to both sides...
y = 3

Answer 7

now you can plot your "y" =)

Answer 8

oh! so its in the 2nd quadrant right?

Answer 9

or in the middle... because x is 0

Answer 10

hello?

Answer 11

it will look like this

Answer 12

yes, i know, but what quadrant is that? its in the middle!

Answer 13

i think if it's in the middle, it would be considered in-between quadrants. if so,
this point would be considered "on the vertical baseline between quadrant I and II"

Answer 14

ok, thanks!
