Graphing Formula: y=mx+b
This formula is used when graphing on a grid. Y represents the y axis which is the vertical line in the center on the graph. X represents the x axis which is the horizontal line which intersects the y axis at the origin of the graph. M represents slope of the line on the graph. B represents the y intercept on the graph.
Standard Form: Ax+By=C
Used for finding the x and y-intercepts.
