How to describe a graph of a linear equation

• A linear equation is drawn as a straight line on a gear up of axes.

• To depict the graph we need coordinates.

• We generate these coordinates past substituting values into the linear equation.

YOU Volition NEED: A whiteboard. a ruler, pen and a piece of squared newspaper.

2 of 8

Step 1 - Draw a table of values for the x and y coordinates. Add the 10 coordinates 0, 1, 2, 3 and 4.

Stride 2 - Using the equation y = 2x + 1, calculate the value of y by using the x value in the tabular array. In this instance, x=0. Exercise the same for 10=1, ten=2, x=3 and x=iv.

STEP 3 - Depict a graph and label the x axis 1 to 4 and the y centrality 1 to 9.

Step five - Draw a line through the coordinates plotted.

How to depict a graph of a linear equation

A linear equation is represented as a line graph. In social club to draw the line graph we crave several pairs of coordinates. These coordinates represent the relationship given in the equation.

For example, for y = 3x , the y value is always equal to '3 lots' of the x value. (1,3), (10,30) and (two.5,7.5) are all coordinates on the line y = 3x.

Frequently a table of values is used to create the coordinates. We employ substitution to calculate the values.

For example y = 2x + ane

The y value is always 'two lots' of the x value plus 1.

We replace the value of x for different numbers and record the resulting y value.
