Let me help. (: Which coordinate is the abscissa? Which is the ordinate? Can you tell me.

Miracrown (miracrown):

it's just a matter of definition, you can look it up.

OpenStudy (anonymous):

Sure . :) abscissa is the x coordinate , ordinate is the y coordinate .

Miracrown (miracrown):

Correct.

Miracrown (miracrown):
