Linearizing Graphs
Graph | Relationship | Proportionality | Modification | Algebraic Equation |
---|---|---|---|---|
Horizontal Line | No | No | No | Y=b |
Vertical Line | No | No | No | X=b |
Positive linear line | Yes | Y is proportionate to x | No | Y=mx+b |
Inverse (graph curving down while x is increasing) | Yes | Y is inversely proportional to x | Y vs. 1/x | Y=m(1/x)+b |
Quadratic (curve that looks like square root graphs) | Yes | Y^2 is directly proportional to x | Y^2 vs x | y^2=mx+b |
Quadratic (normal quadratic graph, only positive half of it) | Yes | Y is directly proportional to x^2 | Y vs x^2 | Y=m(x)^2 + b |
