Answer:

The length of the line segment is 10 units.

Step-by-step explanation:

Let us call the given two points: (x₁, y₁) = (2, -3) and (x₂, y₂) = (8, 5).

The distance between two points, d = $\sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2} }$

Here, $(x_1, y_1) = (2, -3)$ and

$(x_2, y_2) = (8, 5)$

Therefore, distance, d = $\sqrt{(8 - 2)^2 + (5 - (-3))^2$

$= \sqrt{6^2 + 8^2}$

$= \sqrt{36 + 64}$

$= \sqrt{100}$

= 10 units.

Hence, the answer.

Which rule, test, or theorem will help you find the probable number of positive and negative real zeros of a polynomial function

Orlov [11]

The number of positive and negative roots or zeros of a polynomial function is predicted through the Descartes Rule of Sign. This was first described by Rene Descartes in his work La Geometrie. The technique is for determining an upper bound on the number of positive and negative real roots.
