Table of 3 values method and x=0x=0x=0, y=0y=0y=0 (intercept) method
Often considered the easiest approach
Choose 3 xxx-values, calculate yyy-values, plot & draw line
Points that form a straight line
Check your calculations - something has gone wrong
Intercept method
Where the line crosses the xxx-axis
Where the line crosses the yyy-axis
When equation is in form ax+by=cax + by = cax+by=c
Offers more security - can check if points are collinear
Faster method
One error in intercept means entire line is wrong
