Define - "ordered pairs" - ANSWER = (x, y) = a single point on a coordinate plane Define - "origin" - ANSWER = (0,0) = the point where two axes meet Explain - "quadrants" - ANSWER = when the two axes (x and y) cross they form 4 quadrants Explain what - "the distance" means Define - "distance formula" for a line(s) - ANSWER = "distance" - the length between two points on a plane - (x1, y1), (x2, y2) * does not have to be forming a line *distance is ALWAYS positive
