Step-by-step explanation:
The y-intercept is the y-value for when the line intersects with the y-axis. Another way to put this is also the y-value when x=0. This is easy to find when you have a graph because you can simply look to see where on the graph the line intersects with the axis. If you don't have the graph then you can plug 0 in for x in the equation and solve.
The following statement is true about indexes and scales: They rank-order the units of analysis in terms of specific variables.
Indexes provides with a way to make a complex measure that iterate consequence for multiple rank-ordered related questions or statements.
Scale is a type of complex measurement that is combined of several items that have a empirical structure among them.
