Suppose A is a denumerable set and B is an infinite subset of A. P

Lines and Operations 9/7/2016 By Deryn Susman Lines “Rise over run” is a constant called slope (“m”). The slope of the line passes through 2 points. m = (y2−y 1/(x 2x )b A point and a slope determine one line. Slope-InterceptForm y = mx+b Horizontallines havem=0 y=b Verticallines havem=undefined x=constant Operations with Functions Addition: If f and g are functions, the sum of f+g is a rule which operates as follows
