Question

can someone tell me how to write the standard form of a linear equation when all i have is the coordinates (1,2)

Answer 1

Ax + By = C

1A + 3B = C

maybe??

Answer 2

a little more context might be useful ...

Answer 3

You need either two coordinates or one coordinate and the slope.

Answer 4

@zimmah i put the one coordinate up

Answer 5

Yes, but you need either one more, or you need to know the slope. Otherwise there are infinitely many solutions

Answer 6

oh ok well than (1,2) and (4,-2)

Answer 7

@zimmah

Answer 8

Ok, that works

Answer 9

For 3 steps of x, your y decreases by 4

Answer 10

Can you write that part in formula form?
