The difference between successive terms of the sequence is constant.Example:2, 5, 8, 11, 14, ... common difference`common difference:The difference between any two consecutive terms is an arithmetic sequence.  constant of variationGconstant of variation:The number k in an equation of the form y = kx. direct variation?direct variation:An equation of the form y = kx, where k  0. domainUdomain:The set of the first numbers or abscissas of the ordered pairs in a relation. functionifunction:A relation in which exactly one element of the range is paired with each element of the domain. function tablebfunction table:A table used to organize the input numbers, output numbers, and the function rule. linear functionlinear function:A function in which the graph of the solutions forms a line defined by y = mx + b where m and b are real numbers.  line of best fitPline of best fit:A line that describes the trend of the data in a scatter plot.  range of a relationRrange of a relation:The set of second numbers in the ordered pairs of a relation.  riseTrise:The vertical change between any two points on a line on the coordinate plane.  runUrun:The horizontal change between any two points on a line on the coordinate plane.  sequence/sequence:a set of numbers in a specific order.  scatter plot !Rscatter plot:A graph that shows the general relationship between two sets of data slope!slope:The ratio of the change in the y-coordinates (rise) to the corresponding change in the x-coordinates (run) as you move from one point to another along a line. slope-intercept formislope-intercept form:An equation of the form y = mx + b, where m is the slope and b is the y-intercept. system of equationsLsystem of equations:A set of two or more equations with the same variables. term term:each number in a sequence.  y-interceptEy-intercept:The y-coordinate at which a graph intersects the y-axis.8`! q !p 0 < p80 < 0 p R 2 c @yXf@ @ @ Fe  0      0 43"#FR!RlER J`5*I@ J2a0  ! 0! ys 0$\$1̀@&JI*,%JQ*0@u2\@8@ `P S`U@pS0 8`HH>8p <<    0 x x 00xx0````<<``@@(<(<(>
