This study guide on lines in a coordinate plane covers key terms, what different line slopes look like, postulates about parallel and perpendicular lines, the slope-intercept equation, how to graph parallel and perpendicular lines, and...

This applet allows students to practice plotting points and identifying ordered pairs on a coordinate plane. The learning resource consists of the activity, instructions, instructor notes, and additional resources.

The goal of this task is to apply dilations to a triangle in the coordinate plane. Learners will need to find the coordinates of a point which cuts a given segment into one third and into two thirds. The two dilated triangles share a...

The purpose of this task is to use the Pythagorean Theorem and knowledge about quadrilaterals in order to construct squares of different sizes on a coordinate grid. Aligns with G-GPE.B.7.

In this task, 8th graders are shown a picture of a quadrilateral on a coordinate grid and are asked to use the Pythagorean Theorem to find lengths and to explain why the quadrilateral is a rectangle. Aligns with 8.G.B.

[Free Registration/Login may be required to access all resource tools.] Here you will learn how to convert and graph complex numbers in trigonometric or polar form using the polar coordinate system, which is similar in some ways to (x,...

Investigate the first quadrant of the Cartesian coordinate system through identifying the coordinates of randomly generated points, or requesting that a particular point be plotted.

Investigate the Cartesian coordinate system through identifying the coordinates of a randomly generated point, or requesting that a particular point be plotted.

Which stock price had the largest change? How do you know? What is the distance between (a, 5) and (a, -3)? Students continue tracking their investments and work on strategies for calculating length of horizontal and vertical lines.

Create graphs of functions and sets of ordered pairs on the same coordinate plane. This is like a graphing calculator with advanced viewing options.

This is a collection of topics about polar coordinates. There are also links to examples that student can work with.

The goal of this task is to prove the slope criterion for parallel lines. Aligns with HSG-GPE.B.5.

Defines a polar coordinate, pole, and polar axis. Includes graph.

In this task, 8th graders explore congruence and transformations of two triangles on a coordinate grid. Aligns with 8.G.A.2.

This activity allows the user to explore the relationship between slope and intercept in the Cartesian coordinate system.

Build your own polygon and transform it in the Cartesian coordinate system. Experiment with reflections across any line, rotations about any point, and translations in any direction.

Have you ever wondered what the magic kingdom would look like on a coordinate grid?

Students create linear inequalities and systems of linear inequalities on a coordinate plane. This is like a graphing calculator with advanced viewing options.

Use this calculator to calculate the distance between 2 points by entering 2 sets of coordinates in the 3-dimensional Cartesian coordinate system, (X1, Y1, Z1) and (X2, Y2, Z2), to get the distance formula calculation for the 2 points...

The purpose of this task is to help students make the connection between the graphs of sin t and cos t and the x and y coordinates of points moving around the unit circle. Students have to match coordinates of points on the graph with...

Given a point and a definition of a rotation, plot the rotation on a coordinate plane or identify the coordinates of the rotated point.

Choose from a variety of creative problems (tasks) to teach how to create equations in two or more variables to represent relationships between quantities and graph equations on coordinate axes with labels and scales. Explanations and...
