Question

find the x and y intercepts in the equations:
y=x-5
3x+2y=9
5y-4x=20

Answer 1

3 eqs? :O

Answer 2

lol

Answer 3

lol well its on a big packed of questions...i have to do..

Answer 4

packet*

Answer 5

forgot most of this stuff over the summer, now i need some help remembering..

Answer 6

first equation.. if x = 0 then y = -5
and if y = 0 then x = 5

Answer 7

second equation.. if x = 0 then y = 2/9
and if y = 0 then x = 3

Answer 8

I just graphed all 3 lines at once and stared confusedly at my calculator

Answer 9

oh, i c what u want

Answer 10

third equation... if x = 0 then y = 4
and if y = 0 then x = -5

Answer 11

so all you have to do is plug in 0 for x and solve, that tells you the "y intercept"
then just plug in 0 for y... and that gives you the "x intercept"

Answer 12

ok

gracias lol
