Answer:
6
Step-by-step explanation:
Long story short trust me
If the variables are not quantitative we cannot do the arithmetic required in the formulas for r.
<h3>What is a
variable?</h3>
- A variable in mathematics is a symbol and placeholder for a changing quantity or any mathematical object.
- A variable can specifically represent a number, a vector, a matrix, a function, a function's argument, a set, or an element of a set.
Quantitative order:
- Quantitative methods emphasize objective measurements and statistical, mathematical, or numerical analysis of data gathered through polls, questionnaires, and surveys, as well as by manipulating pre-existing statistical data using computational techniques.
- Ordinal-level measurement data can be quantitative or qualitative.
- They can be arranged in ranked order, but differences between entries are meaningless.
- Measurement data at the interval level are quantitative.
- They can be arranged in any order, and meaningful differences between data entries can be calculated.
- We can't do the arithmetic required in the r formulas if the variables aren't quantitative.
Therefore, if the variables are not quantitative we cannot do the arithmetic required in the formulas for r.

Adding both equations
2x=4k
x=2k
y=k
so (2k,k)
