Framing an equation using given condition.Algebraical and graphical representation of given condition.Find ordered pairs of equation.Plotting ordered pairs on same Cartesian plane.Read the common point of intersection of lines when 2 equations are plotted on the same Cartesian plane.

To understand the Algebraic interpretation and graphical representation i.e. intersecting lines implies unique solution, coinciding lines implies infinite solution and parallel lines implies no solution.

Description: In this video students will learn to relate graphical solutions and their algebraic interpretation.

Execution: Teacher will find and plot the ordered pairs on the graph paper. Students will be asked to plot a pair of linear equation in two variables on the same Cartesian plane. They will find the graphical solution and will relate it to their algebraic interpretation.

00:02 Q2. The coach of a cricket team buys 3 bats and 6 balls for Rs 3900. Later, she buys another

bat and 2 more balls of the same kind for Rs 1300. Represent this situation algebraically

and geometrically.

Tried out the canvas response option on @SpiralEducation & it's so awesome! Add text or drawings AND annotate an image! #R10tech

Using @SpiralEducation in class for math review. Student approved! Thumbs up! Thanks.

Absolutely amazing collaboration from year 10 today. 100% engagement and constant smiles from all #lovetsla #spiral

Students show better Interpersonal Writing skills than Speaking via @SpiralEducation Great #data #langchat folks!
