Answer:
A) reflection of P across the x-axis is at (3, 4).
Step-by-step explanation:
The relevant transformations are ...
(x, y) ⇒ (x, -y) . . . . . . reflection across the x-axis
(x, y) ⇒ (-x, y) . . . . . . reflection across the y-axis
__
A) sign of y-coordinate has changed: reflection across the x-axis
B) signs of both coordinates have changed: reflection across both axes
C) sign of x-coordinate has changed: reflection across the y-axis
D) sign of y-coordinate has changed: reflection across the x-axis
The only answer choice that has a proper description is Choice A.
The slope can be obtained by (y2 - y1) / (x2 - x1). In this example, using the two points, we have
(7 - 3) / (8 - 8 ) = 4 / 0.
Division by 0 is undefined.
So, the answer is (d) The slope is undefined.
