The graph of y = 2x + 3 is translated 4 units up and 2 units left. What is the slope of the translated graph?
a.
4
b.
3
c.
-3
d.
2


Solution:

Equation of the graph y = 2x + 3

If the graph translated 4 units up and 2 units left then the equation of the new graph is (y - 4) = 2(x + 2) + 3.

y = 2x + 11
[Add 4 on each side and simplify.]

Image of the graph after the translation is y = 2x + 11.

Slope of the graph y = 2x + 11 is 2.
[Since the equation is in the form of y = mx + c.]


Correct answer : (4)
 22.  
What type of transformation is illustrated in the figure?


a.
Translation
b.
Symmetry
c.
Rotation
d.
Reflection


Solution:

The center of the circle A is moved 5 units down to form the image of the circle with center A'
[From the figure.]

A A'
[Point A goes to point A'.]

So, it is a translation.


Correct answer : (1)

Which transformation should be used to change the Figure-1 to Figure-2?

a.
Reflection
b.
Translation
c.
Rotation
d.
Dilation


Solution:

Figure-2 represents the mirror image of Figure-1.

The transformation used in the Figure-1 to change as Figure-2 is 'reflection'.

So, the correct choice is reflection.
