Question

find 3 solutions for 3x + 7y =0.check out does it pass through origin.

Answer 1

put any three random values of either x or y in the equation to get the other one

1) put x=2

then y= (-6)/7

so the solution is (2,-6/7)

2) put x=4

then y= (-12)/7

so the solution is (4,-12/7)

3) put x= 7

y= -3

so the solution is (7,-3)

to check if the line passes through origin put either x or y=0 if the other one amounts to 0 then it passes through the origin but in this case it doesnt.
