First of all we can rule out that the slope is 10. The coefficient before the x term is not 10 so the answer is not a.
Following on what I said for option a, option b is correct as the coefficient before the x term is -7/8. Therefore the answer is B.
The answer is not C as when x = 0, y is not 0. This means the line does not pass through the origin (0,0)
Option D is not true aswell. When x = 1, y= 9.125. When x= 2, y= 8.25. When x=3, y= 7.375. X is increasing whereas y is decreasing. Therefore option D is ruled out.
The answer is option B.
I hope this has helped you.

ANSWER:
r = 
Explaination:
Convert the given curve into the the polar form.
x = rcosθ
y = rsinθ
in f(x,y) = (x²-y²) - √(x²+y²) = 0
put the values of x & y in given curve equation.
We get at,
g(r,θ) = (r²cos²θ - r²sin²θ) - √(r²cos²θ + r²sin²θ) = 0
g(r,θ) = r²(cos²θ - sin²θ) - √r² = 0
We know that,
cos²θ - sin²θ = cos2θ
g(r,θ) = r²(cos2θ) - r = 0
Solve for r
Finally we get:
r =
The answer would be:
X = -1
Answer:
Following are the response to the given question:
Step-by-step explanation:
Move b a bit further if the angle between cd and ab changes when you move b if you want to make a perpendicular point to cd The angle BEC is 90 ° for making the AB line perpendicular to the line CD to transfer point B to the angle between the two lines.
