What is a independent variable?
a variable that stands alone and isn’t changed by the other variables you are trying to measure
graph y = 3x using independent variable(x), dependent variable, and the ordered pair
independent variable is 0, 1, 2, 3
dependent is 0, 3, 6, and 9
ordered pair (0,0), (1,3), (2,6), (3,9)
