Term Definition
slope the ratio of change in the vertical to the change in horizontal
direct variation a relationship as the independent value increases, the dependent value increases, or as the independent value decreases, the dependent value decreases
slope intercept form given the slope m and the y-intercept of a line, the _______ of an equation is y=mx+b
point slope form for a given point (x,y), on a nonvertical line having slope m, the __________ of a linear equation is: y-y1=m(x-x1)
parallel lines if two non-vertical lines have the same slope, then they are _____
perpindicular lines if the product of the slopes of 2 lines is -1, then the lines are ________. (they are opposite reciprocals)
line of best fit a line that describes, in general, the correlation between two sets of data
midpoint the middle of a line; (x1+x2/2, y1+y2/2)
distance the length of a line; square root(x2-x1)squared+(y2-y1)squared
