If the representation is a graph then use the vertical line test. Draw or imagine straight vertical lines going down the graph. If the vertical line only goes through the function line one time then it is a function. For an example, a circle on a coordinate plane is not a function but a wavy line is.
If the representation is a table with points then look at the x values. If x repeats then it is not a function.
Exactly six units from:
Def'n: Add or subtract 6 to either "x" or "y" in (x,y) = (2, -3)
P.S. (BTW, there are many more ways that are a lot harder to find two orders pairs six units from (2, -3). These are only the easiest.)
1. (2, -3 + 6) = (2, 3)
2. (2, -3 - 6) = (2, -9)
3. (2 + 6, -3) = (8, -3)
4. (2 - 6, -3) = (-4, -3)
Pick from these four. :3
Answer:
20%
Step-by-step explanation:
$187.50 - 20% = $150.00
The answer is c, because it is the same line, just higher.
