The line of reflection is obviously a horizontal line. The only horizontal line in the answer list is ...
A. y = -2

Often, it's not about knowing how to work the problem. It's about being able to eliminate bogus answers and recognizing the form the answer must have.

_____
You can find points on the line of reflection by finding the midpoint between corresponding vertices. Those midpoints are (-4, -2), (-3, -2), and (-1, -2). The line through all three of those points is y = -2.

Solve the equation

Vikki [24]

Answer:

x ≈ - 5.32, x ≈ 1.32

Step-by-step explanation:

Given

x² + 4x - 7 = 0 ( add 7 to both sides )

x² + 4x = 7

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(2)x + 4 = 7 + 4

(x + 2)² = 11 ( take the square root of both sides )

x + 2 = ± $\sqrt{11}$ ( subtract 2 from both sides )

x = - 2 ± $\sqrt{11}$

Thus

x = - 2 - $\sqrt{11}$ ≈ - 5.32 ( to 2 dec. places )

x = - 2 + $\sqrt{11}$ ≈ 1.32 ( to 2 dec. places )
