The graph of the equation x2 + y2 + 8x − 10y − 40 = 0 is which of the following conic sections?

ellipse

hyperbola

parabola

circle

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this
