Draw an empirical linear graph assignment
The weight gain of Goldfish in an aquarium is dependent on different variables such as Temperature, pH (acidity or alkalinity of water), sunlight and the amount of fish food used. If you designed an experiment to find out the weight gain of Gold fish with the amount of fish food for a week, divide all the above variables into three major categories.
Assume that the initial weight of Gold fish was 2 grams each. Draw an empirical linear graph as:
y = mx +b (writing proper variable names in x and y axes and the unit you used.)
