<u>Given</u>:
Given that the graph of the equation of the line.
The line that is perpendicular to the given line and passes through the point (2,-1)
We need to determine the equation of the line perpendicular to the given line.
<u>Slope of the given line:</u>
The slope of the given line can be determined by substituting any two coordinates from the line in the slope formula,
Substituting the coordinates (-1,3) and (2,2), we get;
Thus, the slope of the given line is
<u>Slope of the perpendicular line:</u>
The slope of the perpendicular line can be determined by
Substituting , we get;
simplifying, we get;
Thus, the slope of the perpendicular line is 3.
<u>Equation of the perpendicular line:</u>
The equation of the perpendicular line can be determined using the formula,
Substituting and the point (2,-1) in the above formula, we have;
Thus, the equation of the perpendicular line is
Hence, Option d is the correct answer.
Answer:
galaxies.
Step-by-step explanation:
There are about stars in the universe.
The Milky Way galaxy stars.
All we need to do to find the number of galaxies is to divide the total number of stars in the universe by the number of stars in the Milky Way:
Number of galaxies = (Number of stars in the universe) / (Number of stars in the Milky Way)
Number of galaxies =
N =
N =
The number of galaxies in the universe is approximately .
