Beginning Algebra With Applications, Chapter 5, 5.3, Section 5.3, Problem 46

Graph 3xy=1 by using the slope and y-intercept.

y-intercept:


3xy=1Given equation3(0)y=1To find the y-intercept, let x=0y=1Simplifyy=1


The y-intercept is (0,1)


m=change in ychange in xm=31


Beginning at the y-intercept, move to the right 1 unit and then up 3 units.







(1,2) are the coordinates of a second point on the graph.

Draw a line through (0,1) and (1,2)
