3 Steps Of Graphing Linear Functions

Linear function is a function whose variable is one rank or a function whose graph is a straight line.

There are three steps for graphing linear functions, such as:

1. Determine the intersection with the x-axis, y = 0 obtained by the coordinates A(x₁, 0)
2. Determine the intersection with the y-axis, x = 0 obtained by the coordinates B(0, y₁)
3. Connect two points A and B to form a straight line.

For more details we practice in the example below:

Example :
Draw a graph of y = 2x - 6 !

Answer :

1. Determine the intersection with the x-axis, y = 0
y = 2x - 6
0 = 2x - 6
6 = 2x
6/2 = 2x/2
3 = x
So point A: (3, 0)

2. Determine the intersection with the y-axis, x = 0
y = 2x - 6
y = 2(0) - 6
y = -6
So point B: (0, -6)

3. Connect two points A and B to form a straight line
