When these two lines cross, they make perpendicular lines. They are perpendicular because they cross at right angles to each other
The guideline set by the American Academy of Family Physicians for an e-visit is that E-visits are available only to established patients who have previously received care from the physician’s practice
<h3>What is a Guideline?</h3>
This refers to the set of rules that a process must follow for its smooth running of operations.
Hence, we can see that one of the guidelines that is set by the American Academy of Family Physicians for an e-visit is that E-visits are available only to established patients who have previously received care from the physician’s practice.

The pair two numbers whose difference is 14 and the product is as small as possible (i.e. -49) are (-7,7)
<h3>What are word problems?</h3>
In mathematical concepts, word problems involve a crucial understanding of the problem and knowing which mathematical method and arithmetic operations are best suited to solving the problem.
If we assume that the smaller number should be = a and the larger number = a + 14.
Thus, their product (X) can be expressed as:
= a(a+14)
= a² + 14a
The smallest possible value implies the minimum value, i.e.

Thus,
2a + 14 = 0
a = - 14/2
a = -7
Therefore, we can conclude that the pair of two numbers whose difference is 14 and the product is as small as possible (i.e. -49) is (-7,7).
