Save guides, add subjects and pick up where you left off with your BBC account. To find solutions from graphs, look for the point where the two graphs cross one another. This is the solution point.

In this video we will learn about the plotting of graphs for a pair of linear equations ... Express y in terms of x. To introduce the integral values for x, thus solving for y.

All quadratic functions ... the graph crosses the x-axis. Draw the graph of \(y = x^2 -x – 4 \) and use it to find the roots of the equation to 1 decimal place. Draw and complete a table of ...
