Answer:

2x-y = 1

Step-by-step explanation:

Equation of the line is y-y1 = m (x-x1), where m is the slope and (x1,y1) is a point that lies on the line.

Equation of the given line is,

y-(-1) = 2 *(x-0)

y+1 = 2x

2x-y = 1

8x+16=8x-16 is no solution because it is 32=0
-3x-17=-(17+3x) is infinitely many solutions because it is 0=0
9x+27=27 is one solution because it is x=0
2x-6=6+2x is no solution -12=0

The equation x^2/121 + y^2/1. what points are the vertices of the eclipse

Alla [95]

Answer:

$(-11,0)$ and $(11,0)$ .

Step-by-step explanation:

The given ellipse has the equation:

$\frac{x^2}{121}+\frac{y^2}{1}=1$

This can be rewritten as

$\frac{x^2}{11^2}+\frac{y^2}{1^2}=1$

We compare this to the general equation of the ellipse:

$\frac{x^2}{a^2}+\frac{y^2}{b^2}=1$

We have $a=11$ and $b=1$

The vertices of this ellipse are at $(-a,0)$ and $(+a,0)$ .

Therefore the vertices of this ellipse are at $(-11,0)$ and $(11,0)$ .

The correct choice is A.
