Ck 12: Polar Form of a Complex Number
[Free Registration/Login may be required to access all resource tools.] Here you will learn how to convert complex numbers from rectangular form to polar form. You will also explore the graphs of complex numbers on a polar graph.
Math Open Reference
Math Open Reference: Equations of a Line (Slope and Intercept Form)
The interactive resource investigates slope and intercept. Students adjust the sliders to control the slope (m) and the intercept (b) of the line. The equation and the line will change accordingly. Learners can also drag the origin.
Concord Consortium
Concord Consortium: Quadratic Functions in Vertex Form
Given the equation of a quadratic function in vertex form, students learn to identify the vertex of a parabola from the equation, and then graph the parabola.

Texas Gateway: Determining Intercepts and Zeros of Linear Functions
Given algebraic, tabular, or graphical representations of linear functions, the student will determine the intercepts of the graphs and the zeros of the function.
Concord Consortium
Concord Consortium: Linear Equations: Y=mx+b
Graph lines using a slope and a y-intercept. Identify the slope and y-intercept from the equation of a line in slope-intercept form.
Concord Consortium
Concord Consortium: Linear Equations: Points, Intercepts, and Slopes, Oh My!
Learn how to graph lines with two methods: using x- and y-intercepts and using point-slope form.
Khan Academy
Khan Academy: Features of Quadratic Functions: Strategy
Identify the form of a quadratic function that immediately reveals a given feature of that function. Features in question are the y-intercept of the graph, the zeroes ('roots') of the function, and the vertex of the parabola.
