True or false: the point, line, and pair of intersecting lines are special types of conic sections

Yes it is true that point , line and pair of intersecting lines are special cases of conic sections

They are actually degenerate cases of intersection that occurs in special conditions.

Lets get into a bit detail one by one

A single point - when the plane which cuts the surface of cone only passes through apex

Again when the plane passes through apex and another point on the cone

it produces one straight line or two intersecting straight lines.

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

the answer to the question is a

step-by-step explanation:

it has the same slope and the same y-intercept.

y + 11 = -7/9(x - 18)

y + 11 =-7/9x + 14

b

y = -7/9x + 3

y-intercept (0, 3)
