What in general is the value measured by the horizontal axis called?
The variable plotted along the horizontal (x) axis is termed the independent variable. The variable plotted along the vertical (y) axis is termed the dependent variable. Usually equations of curves are given in the form y = f(x) meaning that the y value is dependent on the x value.

The chemical composition and physical state of substances can change during an experiment.For example two reactants in solid or liquid form can react in an experiment to give a product in a gaseous form.
What serves as a standard of comparisons to evaluate the effect of the independent variable on the dependent variable variable?
There cannot be one since the answer depends on the form in which the effect is measured: whether the effect is qualitative or quantitative. There are various non-parametric measures of correlation or concordance. For data that are more quantitative there are more powerful tests such as the F-test for independent Normal distributions.
What is slack variable?
Slack variable is a variable that is added to a constraint to switch form an inequality to equatlity equation.
