The anwser to your question Is letter B
y = -3x - 2
Since a < 0 we have a decreasing line, so it can be only the first or the last
And if we solve the equation for y = 0 we have
0 = -3x - 2
3x = -2
x = -2/3
So, the last one is the right
Answer:
An ellipse
Step-by-step explanation:
Take a cone and make a diagonal cut through it, removing a very thin slice. The result is an ellipse.
a /\
/ \
/ \ b
/ \
Make a straight line from a to b, it will make an elliptical shape. If we cut perfectly horizontally, we would get a circle, when we angle the cut of our cross section, the shape gets more and more elliptical depending on the angle of the cut
