Step-by-step explanation:
<u>Equation of a Line</u>
We can find the equation of a line by using two sets of data. It can be a pair of ordered pairs, or the slope and a point, or the slope and the y-intercept, or many other combinations of appropriate data.
We are given a line

And are required to find a line perpendicular to that line. Let's find the slope of the given line. Solving for y

The coefficient of the x is the slope

The slope of the perpendicular line is the negative reciprocal of m, thus

We know the second line passes through (2,3). That is enough information to find the second equation:


Operating

Simplifying

That is the equation in slope-intercept form. Intercept: y=4
Answer:
p = - 5i or p = 5i
Step-by-step explanation:
Noting
= i
Given
p² = - 25 ( take the square root of both sides )
p = ±
= ±
= ± 5i
Thus
p = - 5i or p = 5i
The question is a scientific inquiry. The explanation does not fit any of the four.
