Lesson Ch 5 L 5 Extension Lesson NON LINEAR EQUATIONS NON LINEAR EQUATIONS Equation whose graph does not form a straight line (linear) is called a Nonlinear Equation Equation whose graph does not form a straight line (linear) is called a Nonlinear Equation

How can you tell if it is nonlinear 2 ways!! 2 ways!! 1 st way is to graph it! If it is curved line (not straight) when you graph it then it is nonlinear. 1 st way is to graph it! If it is curved line (not straight) when you graph it then it is nonlinear.

2 nd way 2 nd way Look at the function table Look at the function table XY XY constant Constant: changes by the same amount Variable: changes by different amounts If both sides are constant, it is linear. If both sides are different, it is nonlinear. constant variable

Lesson Ch 5 L 6 Slope: is the steepness of the line Slope: is the steepness of the line Slope = rise (change in Y) Slope = rise (change in Y) run (change in X) run (change in X) Positive Negative

Choose any two points on your line. Count up from the bottom dot and Then go left or right. Up 3 Left 4 (think when we go left it is negative) ¾ is the slope Since this is a negative line it is -3/4 (simplify this if you can) Up 3 Left 4

Special lines

Interpreting slope We can also use what we know about slope to interpret the meaning of graphs. We can also use what we know about slope to interpret the meaning of graphs. Keep in mind when we do this ALWAYS put Y over X. Keep in mind when we do this ALWAYS put Y over X. Y axis per X axis (look at their labels) Y axis per X axis (look at their labels)
