Algebra Tools: lines, binomials, parabolas, units and more

This TI-83 Plus and TI-84 Plus algebra program contains many useful features. The program will perform all of the following: calculate distance; solve for missing x and y coordinates in the distance equation; calculate the midpoint of a line; calculate endpoint of a line; calculate the slope of a line; calculate X and Y intercepts of a line; solve a system of equations written in standard, point slope, or slope intercept form; solve the quadratic formula and show the work; complete the square; multiply 2 binomials (FOIL); finds the vertex, and axis of symmetry, of a parabola, determine whether the vertex is the max or min, and whether it opens up or down; factor trinomials; solve the growth and decay formulas; convert units of measurement and temperature; reduce radicals; show positive factor pairs of a number; find the geometric mean of 2 numbers; and enhance the graphing screen controls.
