Linear A graph with the equation y = mx + b
slope formula (y₂- y₁) / (x₂- x₁)
slope the steepness of a line on a graph, equal to its vertical change divided by its
horizontal change
parabolic another term is exponential or quadratic
equation for a parabola y= kx^2 or y^2=kx
constant what does k represent in an equation?
Inverse equation y=k/x
inverse squared equation y=1/x^2
to find the constant for an inverse graph multiply an x and a y value times each other
