Question

Find the intercepts for the graph of the equation given.

4x-7y=84.

Find the x-intercept.

Find the y-intercept.

I keep working on this problem, but I keep getting stuck, I don't know what I am doing wrong.

Answer 1

divide whole equation by 84 you'll get 4/84*x-7/84*y=1 and then you'll have x/21-y/12=1 hence the denominator of x and y are the intercepts..because the intercept form of equation of line is x/a+y/b=1 where a and b are intercepts

Answer 2

you'll have (21,-12)

Answer 3

Thanks, I forgot all about dividing. Now I just have to check and see if it simplifies.

Answer 4

okay...hope you'll get the answer

Answer 5

I hope so to.

Answer 6

what you got?

Answer 7

Well, to be honest right now I feel very dumb lol. I forgot how to simplify these things.

Answer 8

noo worries it's just 4/84 for x intercept and 7/84 for y now after solving you'll get x intercept = 21 and y= -12 for further query check out above mentioned comments

Answer 9

Lol, alright. I hate math like this it always gives me a headache.

Answer 10

it's easy ...play with it :)

Answer 11

Lol, not easy for me. I can never get it to stick in my head.

Answer 12

okay give a try ..and if you're stuck...just ask for it... :)
