Answer:
y = -(1/2)x
Step-by-step explanation:
given 8x-4y=12
arranging in slope-intercept form:
8x-4y=12
4y = 8x - 12 (divide both sides by 4)
y = 2x - 3
we can see that the slope of this line is the coefficient of x , which is 2.
The slope of a perpendicular line is the negative reciprocal of this number
m = -1/2
assembling the linear equation in point-slope form
y - y₁ = m (x - x₁)
given that the equation passes through the origin, then both x₁ and y₁=0
y - 0 = (-1/2) (x - 0)
y = (-1/2)x
y = -(1/2)x
The coordinates of P(x, y) is: A. P(Negative StartRoot 21 EndRoot, –2)
<h3>Coordinates of P(x, y)</h3>
Given:
Radians=3π/2
theta=-5/2
Hence:
Hypotenuse = - 5
Altitude = 2
Using Pythagorean theorem
Hypotenuse² = Altitude² + Base²
-5²= 2² + Base²
25 ² - 4 ² = Base²
Base = √21
Thus P(x,y) :
= P(-√21 : -2)
Therefore the correct option is A.
