Plotting linear graphs Going from rule to graph. To sketch a linear graph from a rule, determine two points that satisfy the rule and connect them with a straight line. Two commonly used methods are: ...

Graphing a linear function. To graph a linear function: 1. Find 2 points which satisfy the equation. 2. Plot them. 3. Connect the points with a straight line. Example: y = 25 + 5x. let x = 1 then y = ...

Linear equations can be shown on a graph. Find out how to create one in this Bitesize KS3 maths video. ... For example, for y = 3x, the y value is always equal to '3 lots' of the x value.

Worked Example Both equations in the form \(Ax+By=C\) Solve the following pair of simultaneous equations: \[\begin{align} 3x + 4y &= 23\\ 5x - 2y &= 10 \end{align}\] ... To find these conditions, we ...

Linear functions are known for their straight ... After giving them a few examples, the teacher can ask them to identify other situations where exponential growth is present, such as population growth ...

Capture relationships between data sets by graphing linear equations in Microsoft Excel 2007. ... For example, if you are graphing the relationship between marketing spending and revenue, ...

Techniques of linear graph theory are applied to the study of switching networks. The first part treats the relationships among paths and circuits in a graph which will give a simple method of ...

An example of the use of slope in economics. The demand for a breakfast cereal can be represented by the following equation where p is the price per box in dollars: d = 12,000 - 1,500 p. This means ...

They can then plot this data on a graph and assess whether the function is linear or nonlinear. 3. Modelling: Modelling is an activity that encourages students to create mathematical models that ...
