Define - "ordered pairs" CORRECT ANSWER = (x, y) = a single point on a coordinate plane Define - "origin" CORRECT ANSWER = (0,0) = the point where two axes meet Explain - "quadrants" CORRECT 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) CORRECT 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 = (Distance (d) = "square root" all over - [( x2-x1)^2 + (y2-y1)^2] Explain what - "the midpoint" means Define - "midpoint formula" for a line(s) CORRECT ANSWER = "midpoint" - the middle point between two points on a plane - (x1, y1), (x2, y2) -that are forming one line *remember - "MidPOINT" = Midpoint (M) = [(x1+x2)/2] , [(y1+y2)/2] Coordinate Plane = ______________ demential. CORRECT ANSWER = 2D
