coordinates | a pair of numbers that identifies a point on the coordinate planeāthe first number is the x-value and the second is the y-value |
rise | vertical change between two points |
run | horizontal change between two points |
slope | the ratio of the vertical and horizontal changes between two points on a surface or a line |
slope formula | the equation for the slope of a line, written as , where m is the slope and (x1, y1) and (x2, y2) are the coordinates of two points on the line |
