Answer:
Graph the points (10,4) (20,8) (30,12) (40, 16)
Step-by-step explanation:
The Days are the independent variable, they dictate the Hight of the plant. The Hight is the dependent variable. The independent variable on a graph is always x, and the dependent variable is always y. So because of this we can find that the time is x, and the Hight is y. Now we can easily make our coordinate pairs. Once the points are graphed simply draw straight line through them.
I hope this helped :)
