And so, y is the dependent variable, x is the independent variable. And because everyone says so, we plot independent on the x-axis, dependent on y-axis.
The curriculum must be very different where you live. I learned about independent and dependent variables the first week of 6th grade. My science teacher made us come up with them all on our own like every week for our labs.
independent variable: the variable that shows that no one asked to learn about variables
dependant variable: the variable that shows that no one cares about variables
