Question

Please help me I don't understand?? study guide :(

Answer 1

what are the coordinates of the x- intercept of the line 3x4y=12

Answer 2

I know what the answer is (4,0) but why?

Answer 3

to get x-intercept, put y=0 in line 3x+4y=12

Answer 4

like hartnn is saying

3x+4y=12

3x+4(0)=12 ... plug in y = 0

3x + 0 = 12

3x = 12

x = 12/3

x = 4

So the x-intercept is the point (4,0)

Answer 5

to find the y-intercept, just plug in x = 0 and solve for y

Answer 6

Thank you Thank you for your help :)

Answer 7

yw

Answer 8

do you mind giving me a practice problem? So I can figure it out myself i really appreciate it

Answer 9

find the y-intercept of 5x + 10y = 30

Answer 10

just make up one please :)

Answer 11

to get y-intercept, put x=0 in 5x+10y=30

Answer 12

since my test is multiple choice can you give me answers to choose from?

Answer 13

not required, but sure,
1) (0,-3)
2) (0,3)
3) (3,0)
4) (0,6)

Answer 14

having problems ?

Answer 15

yes i got x=10?

Answer 16

I suck at math

Answer 17

how you can get x=10 when i told you to put x=0 to find y-intercept :O

Answer 18

i have no idea why
