No matter how it is written, it still is a line. A video shows class members how to take points and write the equation of the line that goes through those points. It then outlines how to develop the equation whether the points are presented in a table or on a graph. The presenter then demonstrates how to write the equations in point-slope, slope-intercept, and standard form.

Concepts

linear equations, linear equations writing, point-slope form, standard form, slope-intercept form, slope formula, table of values
