In simple regression analysis the quantity that gives the amount by which y (dependent variable) changes for a unit change in x (independent variable) is called the:

Slope of the regression line

Step-by-step explanation:

In simple regression analysis, the slope is the parameter that describes the rate of change of the dependent variable as a function of an unit change of the independent variable. In the following general linear model, the slope is represented by 'm':

1. X= vinegar, Y= oil

2. o=1.5v
