Question 313624: Draw a graph of the line with slope -3 and y-intercept (0,2).
Answer by rapaljer(4671) (Show Source):
You can put this solution on YOUR website! The equation of the graph is y = mx +b where m is the slope and b is the y-intercept. If you use a graphing calculator, graph y = -3x+2.
However, if you don't use a calculator, start with the point on the y axis, (0,2). From this point go DOWN three units, and to the RIGHT 1 unit. Put a point there, and connect the dots.
You really need to see my own website for all the FREE resources that I have there, including my OWN explanation of GRAPHING. To see my website, click on my tutor name "Rapaljer" anywhere in algebra.com. On my information page, click on the link to my website. Look for the link on my Homepage "Basic, Intermediate, and College Algebra: One Step at a Time." Choose "Basic Algebra", then "Chapter 4 (GRAPHING)". This is my OWN non-traditional explanation, complete with examples, exercises, and ALL of the answers, that my own students found much easier to understand than the regular textbooks. See also my "Math in Living Color" pages that go with this section. In these pages, I explain the solutions to many of the exercises IN LIVING COLOR!!
See also the vidoes, made from my own classes a few years ago before I retired. The video you need to see is called "Graphing and Slope of a Line". These videos are now available FREE on my website. From my Homepage, look for the link "Rapalje Vidoes in Living Color". Choose "Basic Algebra." Look for topic on Graphing.
