Answer 1

Answer:

a) (x=6); b) (x= -5.5)

Step-by-step explanation:

find the midpoint of each of the pairs of coordinates.

((x1 + x2)/2 , (y1 +y2)/2)

Answer 2

Find mid points

#1

• (3,2)
• (9,2)

$\\ \rm\rightarrowtail (\dfrac{3+9}{2},\dfrac{2+2}{2})$

$\\ \rm\rightarrowtail (\dfrac{12}{2},\dfrac{4}{2}$

$\\ \rm\rightarrowtail (6,4)$

We know x is fixed

So Axis of symmetry=x=6

#2

• (-18,3)
• (7,3)

$\\ \rm\rightarrowtail (\dfrac{-11}{3},2)$

$\\ \rm\rightarrowtail (-5.5,2)$

Axis of symmetry

• x=-5.5
