19. P(4, -2)
20. P(0, -6)
21. P(-3, -4)
Answer:
see below
Step-by-step explanation:
When you're doing a bunch of these, it is helpful to make a table with reminders as to how they're calculated. That table is shown below.
__
In the attached, we have used ...
r² = x² +y²
√20 = 2√5
√36 = 6
√25 = 5
and 1/(2√5) = √5/10. (The division is outside the radical.)
Answer:
x= -5
Step-by-step explanation:
just graphed it . y = 4 is a flat horizontal line.
x=5 is a vertical line that passes through (5,2)
The equation of the perpendicular line is x = 5.
To find the equation of a line perpendicular to y = 4 that passes through the point (5, 2), we need to determine the slope of the original line. The equation y = 4 represents a horizontal line with a slope of 0. Perpendicular lines have slopes that are negative reciprocals of each other. The negative reciprocal of 0 is undefined, so the equation of the perpendicular line will be x = 5.
