Brief Review: Linear Equations in Standard Form December 4, 2013

We just posted a Brief Review PowerPoint on linear equations in Standard Form. While a lot of focus is rightly placed on linear functions in slope intercept form, the standard form is sometimes where such an equation starts. Click here to see the PowerPoint on Media4Math+.
In our Brief Review we go through a worked example showing how to derive the Standard Form equation and how to convert it to Slope Intercept form. In the process we use our Math Solver.
We provide a SlideShare version of this PowerPoint here.

New Math Solver: Converting from Standard Form to Slope-Intercept Form December 3, 2013

Media4Math has just posted a new Math Solver, one that walks through the steps of converting a linear equation in Standard Form to Slope-Intercept Form. This is an important skill for students to focus on, since many word problems start out as linear equations in Standard Form that then need to be converted to Slope-Intercept Form.
This is how the Solver works. Recall that an equation in Standard Form looks like this:

Ax + By = C

Our Math Solver takes values for A, B, and C as inputs.

After inputting the values for A, B, and C, press Solve. A detailed solution is shown.

Use our Math Solvers to produce worked-out examples that use your inputs. Students can use them to check homework. They can also be used for developing Tutorials.

In our latest issue of Math in the News, we look at the recently launched LADEE Mission to the Moon. This unmanned mission will send a robotic probe to the Moon to the study its atmosphere. This provides us with an excellent opportunity to explore the mathematics of space travel.

In particular, we look at several equations having to do with rocketry. We explore how these equations arise, specifically from the conservation of momentum. What propels the rocket upward is the thrust from the expelled rocket fuel, and this upward motion results from Newton’s Third Law of Motion. We also look at how the changing mass of the rocket, as it burns fuel, aids in its acceleration.

We reproduce our Math in the News issue here as a Slideshare Presentation.
