LO:To plot linear relationships on the Cartesian Plane
Know:
- What a linear equation is..
- How to use co-ordinates to plot points.
Understand:
- That linear equations can be used as graphical representations to show a linear relationship on the Cartesian Plane.
Do:
- I can plot linear relationships on the Cartesian plane.
Linear Relationships
Linear relationships show a steady increase or decrease between two variables.
In this case, distance and time have a linear relationship as the distance is 25 times the value of the time.
For every 1 unit of time it increases, the distance increases by 25 units.
How to Graph Linear Relationships
To graph linear relationships, you need to first set up a T-Chart.
Then you insert values for “X” and find out the corresponding values for “Y”. In this case when X = -3, then Y = 1 and when X = -2 then Y = 2.
Once you have values for X and Y, you can use those values as co-ordinates and plot that on the Cartesian Plane.
