In this video we are going to focus on mistakes that students make when they need to solve a system of equation by graphing ...

To solve a system of equations means to obtain a common x-value and a common y-value that makes each of the equations in the system true. To solve a system of equations by graphing means to obtain the ...

Master simultaneous equations with this no-prep graphical worksheet! Covers finding intersections from graphs, verifying coordinate solutions, and determining parallel/coinciding systems. Includes ...

In order to graph linear equations by finding intercepts, we must remember what an x and y intercept are. So remember that in an x-intercept it’s the y that equals zero, and for the y-intercept it’s ...

A worksheet on determining whether a point is on a line and the graph of a line. The exercises require to: Detailed solutions are included. Are your secondary algebra students struggling to understand ...

Sometimes, while writing my own textbook, I find myself questioning whether something deviates from the norm. The other day, ...

The iPad Calculator app has introduced an innovative feature called Math Notes, designed to enhance how you interact with mathematical equations. By integrating handwriting recognition, real-time ...

A linear equation is drawn as a straight line on a set of axes. To draw the graph we need coordinates. We generate these coordinates by substituting values into the ...

Simultaneous equations like 𝒚 = 2𝒙 - 1 and 𝒚 = 𝒙 + 1 can be represented graphically. To solve the equations graphically, the two lines 𝒚 = 𝒙 + 1 and 𝒚 = 2𝒙 - 1 are drawn on the same diagram.

Grade school math students are likely familiar with teachers admonishing them not to just guess the answer to a problem. But a new proof establishes that, in fact, the right kind of guessing is ...
