<h3>
Answer: A) parabola</h3>
Some degenerate parabola cases form a single straight line, while other cases form one pair of parallel lines.
A degenerate hyperbola forms two lines that intersect at the vertex of the cone. We can rule out choice B.
A degenerate circle is a single point, so we can rule out choice C.
A degenerate ellipse is also a single point. Any circle is an ellipse (but not the other way around). We can rule out choice D.
Is This Substitution?
Cause if it is, then Y = 3x - 4
Y = 4 + x
= (4, 8)
Answer:
<h3>
B.</h3>
Step-by-step explanation:
The distance between two any points <em>a</em> i <em>b</em> is |a-b| as we don't know which of them is larger number.
So:
a=-2 and b=1 means distance |-2-1| = |-3| = 3
{If we know the value of given points we can subtract the smaller one from the larger. It also works: -2<1, so the distance would be 2-(-1)=2+1=3}
