Mathematics
1 answer:
Lubov Fominskaja [6]4 years ago
7 0

The <em><u>correct answer</u></em> is:

Rotation of 90° counterclockwise about the origin  and a translation 2 units right

Explanation:

A rotation 90° counterclockwise maps each point (x, y) to (-y, x).  This means our points would be:

A(-4,3)→(-3, 4); B(-1,3)→(-3, -1); C(-2,1)→(-1, -2)

A translation 2 units right will add 2 units to the new x-coordinates; this gives us

(-3, 4)→(-1, 4); (-3, -1)→(-1, -1); and (-1, -2)→(1, -2)

These are the points in the image, so this is the correct set of transformations.

Answer:

<em>a ) y = 2,</em>

<em>b ) x = 5,</em>

<em>c ) x = - 3,</em>

<em>d ) y = 4</em>

Step-by-step explanation:

a )                                                                                  

( - 3, - 4 ), ( 0, y )\\Slope = - 4 - y / - 3 - 0\\2 = - 4 - y / - 3,\\\\- 6 = - 4 - y,\\- y = - 2\\\\y = 2                                                            

                                           

b )                                                    

( - 2, 2 ), ( x, 5 )\\Slope = 2 - 5 / - 2 - x,\\3 / 7 = - 3 / - 2 - x,\\\\( Algebra ) x = 5

c )    

( x, 5 ), ( 1, - 5 )\\Slope = 5 - ( - 5 ) / x - 1\\- 5 / 2 = 5 + 5 / x - 1,\\- 5 / 2 = 10 / x - 1\\\\( Algebra ) x = - 3

d )

( -6, y ), ( 8, 2 )\\Slope = y - 2 / - 6 - 8,\\- 1 / 7 = y - 2 / - 14\\\\( Algebra ) y = 4

<em>Hope that helps!</em>
