128003713	relation	any set of ordered pairs
128003714	slope-intercept form	a linear equation written in the form y=mx+b
128003715	ordered pairs	a pair of numbers used to indentify a point in a plane
128003716	slope	m
128003717	y cordinate	the second number in an ordered pair
128003718	direct variation	an equation of the form y=kx
