1 G302 - Graphing Techniques Applied to Earth Science I. Graphing Review A. Purpose of graphing - to plot data and allow general relationships to be visualized. B. Basic X-Y (scatterplot) graph 1. Axis a. Y axis = vertical axis (ordinate) b. X axis = horizontal axis (abscissa) C. Graph Trends (see attached figures) 1. Linear Increase / Decrease 2. Constant 3. Parabolic (curvilinear) Increase / Decrease Linear Increase Constant Parabolic D. Determining Slopes of Lines 1. slope of any line on a graph = rise / run = (Y 2 - Y 1 ) / (X 2 - X 1 ) Positive Slope Negative Slope Zero Slope Undefined Slope

2 E. Linear Relationships - represented by uniform change of y relative to x 1. General Equation for Line: Y = mX + B where Y = variable on ordinate axis, X = variable on abcissa, m = slope of line, B = y-intercept (value on y axis where line intercepts it) a. Sloping line downward to right = negative slope b. sloping line downward to left = positive slope F. Relationships other than linear 1. Quadratic Equation a. form: Y = aX 2 + bX + C where y is a function of x, while a,b, and c are constants 2. Polynomial Functions of higher order (expanded quadratic equation) a. e.g. form: Y = aX

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
