Slopes of Paralle & Perpendicular Lines (See notes attached)

Class/homework:  page 349-351  #3,4,8(a,b), 10a

Quiz Wednesday (Similar to warm up) :  Know Slope of Horizontal is zero and vertical lines have slope undefind, Perpendicular Slopes have opposite reciprocals and parallel lines have equal slopes, Know which number represents the y-intercept and slope in and equation given in the form y=mx+b,  calculate slope when given two points, given a slope know the slope of a line that is perpendicular or parallel to it.  Know that intercepts are points on a line so it can be used to find slope.  Given a word problem, write the equation in the form y = mx+b
