Question 1 (5 points)

Find the coordinates of the reflected image.
A triangle with vertices F(-1,9), G(-2, 1), and H(-7, 4) is reflected over the x-axis.
O
F'(-1,-9), G'(-2, -1), and H'(-7, -4)
O F"(-1,9), G (-2, 1), and H'(-7, 4)
OF'(1,-9), G'(2, -1), and H'(7,-4)
O F'(-9, -1), G'(-1,-2), and H'(-4,-7)

Answer 1

Answer is A. F'(-1,-9), G'(-2, -1), and H'(-7, -4)

Explanation:

Answer 2

A. F'(-1,-9), G'(-2, -1), and H'(-7, -4)

Explanation:

A reflection over the x-axis has the rule

`(x,y)\rightarrow (x,-y)`

You are given a triangle with vertices F(-1,9), G(-2, 1), and H(-7, 4). After reflection the vertices of new triangle F'G'H' will have coordinates

• 
  `F(-1,9)\rightarrow F'(-1,-9);`
• 
  `G(-2,1)\rightarrow G'(-2,-1);`
• 
  `H(-7,4)\rightarrow H'(-7,-4).`
