Answer: Ok, there are two types of variables, the independent and the dependents.
a dependent variable is one that changes in response to the independent variable.
In an experiment, yo usually have control over the independent variable, it may be the temperature on an oven, the intensity of an x-ray cannon, the time you let something heat under the sun, etc.
and the dependent variable will response to the independent variables in some way, so if you can observe how it changes you can understand te relationship between them, that is the goal of the experiment.
So it's true, yo want to know how the response variable "responds" to the treatment you apply.
Every time the x-value increases by 1, the y-value increases by 2. Therefore, the slope of the line must be equal to (rise/y-values over run/x-values). In slope-intercept form , represents the slope of the line, represents the y-intercept, and represents any point the line passes through.
Since represents the slope of the line, the value of
While the question only asks for this value, it's good to note that the equation of the function is (find 7 by substituting any ordered pair in the table with ).
