Best ResponseYou've already chosen the best response.2I know what the answer is (4,0) but why?

Best ResponseYou've already chosen the best response.3to get xintercept, put y=0 in line 3x+4y=12

Best ResponseYou've already chosen the best response.1like 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 xintercept is the point (4,0)

Best ResponseYou've already chosen the best response.1to find the yintercept, just plug in x = 0 and solve for y

Best ResponseYou've already chosen the best response.3not required, but sure, 1) (0,3) 2) (0,3) 3) (3,0) 4) (0,6)

Best ResponseYou've already chosen the best response.3how you can get x=10 when i told you to put x=0 to find yintercept :O

Best ResponseYou've already chosen the best response.2sorry i got it though it would be (3,0) yes

Best ResponseYou've already chosen the best response.3you got y=3 then, right ?? and intercepts are of the form (x,y) y coordinate comes after comma so, would you like to revise your answer ?

Best ResponseYou've already chosen the best response.2okay i know this is wrong but is it (0, 2 1/3)

jim_thompson5910

Best ResponseYou've already chosen the best response.1to find the xintercept, you plug in y = 0 not x = 0

hartnn

Best ResponseYou've already chosen the best response.3to get xintercept, you need to put y=0, right ?

Best ResponseYou've already chosen the best response.12x+3y = 7 2x+3(0) = 7 ... plug in y = 0 (not x = 0) 2x + 0 = 7 2x = 7 x = ???

Best ResponseYou've already chosen the best response.3x=3 1/2 is correct, but same note again, intercepts are of the form (x,y) x coordinate comes before comma so, would you like to revise your answer ?

Best ResponseYou've already chosen the best response.2No way i got it right and yes :) (3 1/2,0)

hartnn
