Using Excel's Exact Function By using the Exact function in cell C1, you can ask Excel to indicate whether the number in cell A1 exactly matches the one in B1. If the numbers match, Excel returns a value of TRUE. If the numbers don't match, Excel returns a value of FALSE.

Two variables x and y have a deterministic linear relationship if points plotted from (x,y) pairs lie exactly along a single straight line. In practice it is common for two variables to exhibit a relationship that is close to linear but which contains an element, possibly large, of randomness.

ANSWER: Sample answer: You can determine whether each element of the domain is paired with exactly one element of the range. For example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.

If you don't have a graph, you can tell if 2 variables are directly proportional by writing down the equation of the line. If you can use algebra to rewrite the equation to read y=kx, wherein y = the y coordinate, k = the constant, and x = the x coordinate, then the variables are directly proportional.

The relationship between variables can be linear, non-linear, proportional or non-proportional. A proportional relationship is a special kind of linear relationship, but while all proportional relationships are linear relationships, not all linear relationships are proportional.
