(8, –98)
(–9, 105)
(3, –39)*


2. Find three solutions of the equation.
y = 2x – 6
(–2, –10), (1, –4), (2, –1)
(–2, –10), (1, –4), (0, –6)*
(0, –6), (3, –2), (–2, –10)
(1, –4), (0, –6), (–1, –9)



3. Which pair of points has a positive slope?
(–2, 9), (1, –9)*
(–2, 5), (2, –11)
(–2, –15), (4, 21)
(–2, 13), (1, –11




4. The ordered pairs (2, –21) and (5, –45) are solutions to which of the following equations?
y = –8x – 5
y = –8x + 5
y = 8x – 5
y = 8x+ 5*


5. Which is a rule that describes the translation of a point from (–5, 4) to (–1, 2)?
(x, y) (x – 4, y – 2)
(x, y) (x + 4, y – 2)*
(x, y) (x + 4, y + 2)
(x, y) (x – 4, y + 2)


6. ΔJKL has vertices J(10, 5), K(2, 8), and L(4, 9). It is translated right 5 units and up 4 units. What are the
coordinates of J’, K’, and L’?

J'(15, 9), K'(12, 7), L'(9, 13)
J'(15, 9), K'(7, 12), L'(9, 13)
J'(14, 10), K'(6, 13), L'(10, 12)*
J'(15, 5), K'(7, 8), L'(9, 9)


7. The point M(x, y) is reflected over the x-axis. Use arrow notation to describe the original point and its
reflection.

(x, y) (x, y)*
(x, y) (–x, y)
(x, y) (–x, –y)
(x, y) (x, –y)

Answer 1

I did not answer your question the first time you posted it, since it looks like an obvious "homework dump"
The first 4 questions simply require that you sub in the values and test.

#5, what happened to the x and to the y value of the original point?
-looks like 4 was added to the x, and 2 subtracted from the y
Now, which of the choices says that ?

#6 , take point j(10,5) . now add 5 to the x and 4 to the y. What do you get?
do that to the other points.

#7
suggestion:
take any point you feel like and plot it.
Now reflect it in the x-axis. What are the new coordinates?
Which choice matches that???

Answer 2

yes

Answer 3

yes

Answer 4

WHAT that was so not helpful?!
