Difference between cartision system and linear graph with defination and how to do it
Dear student
CARTESIAN SYSTEM
A Cartesian coordinate system, also known as rectangular coordinate system, can be used to plot points and graph lines.
The following is an example of rectangular coordinate system.
It is basically, a set of two number lines
The horizontal line is called x-axis and the vertical line is called y-axis
A good real life example of a vertical number line or y-axis is a thermometer.
Notice that it has 4 quadrants.
In quadrant I, x and y are positive
In quadrant II, x is negative, but y is positive
In quadrant III, x and y are negative
In quadrant IV, x is positive, but y is negative
The center, or intersection of the two axis is equal to (0,0)
A point is represented by a pair of numbers (x, y)
x stands for any value on the x-axis and y stands for any value on the y-axis
An example of a point is (1, 5)
Let us now plot some points.
Locate point (2,3).
x = 2 and y = 3
Draw a vertical line at x = 2 and draw a horizontal line at y = 3
Where the two lines meet or intersect, is your point (in red)
LINEAR GRAPH
A linear graph is a graph that explains a linear relationship between the variables. Basically it is a line graph.
