The point (–3, 5) has been reflected so that the image is at (5, –3). what is the line of reflection?
a. x-axis
b. y-axis
c. y = x
d. y = –x

The point (-3, -8) is reflected in the y-axis. What is the image of this point?

The point (2, 4) is reflected in the line x = -3. What is the image of this point?

The point (a, b) is reflected in the line y = x. What is the image of this point?

ΔXYZ is defined by its vertices X(1,3), Y(-3,5), and Z(0, -5). ΔXYZ is reflected in
the y-axis. What are the coordinates of its image X’Y’Z’?

The translation T: (x, y) → (x -2, y + 4) maps the point (2, -3) to

The translation T: (x, y) → (x + 3, y - 2) maps the point (-4, -3) to

So what is the correct answer of the choices?

A.   x-axis

B.   y-axis

C.   y = x

D.   y = –x

Choice B marked me wrong...  ;-(

Step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
