Start with the formula:    h=k \t    
Substitute the values  :<span>   2=k\65         
</span><span>
then solve for</span> k:           k=130    
 
        
             
        
        
        
X₁ + X₂ / 2   & Y₁ + Y₂ / 2 ------------- This is the formula to plug in the coordinates. 
3.5 + 1.5 / 2= 2.5      2.2 + (-4.8) / 2= -1.3
Answer = (2.5,-1.3)

You haven't provided the original coordinates or the figure, therefore, I cannot give an exact answer. However, I will help you with the concept.
For rotation 180° about the origin, the signs of both the x any y coordinates are changed.
<u>This can be modeled as follows:</u>
(x,y) ......> rotation 180° about the origin ........> (-x,-y)
<u>Examples:</u>
(1,2) .......> rotation 180° about the origin ........> (-1,-2)
(2,-19) ....> rotation 180° about the origin ........> (-2,19)
(-3,-8) .....> rotation 180° about the origin ........> (3,8)
(-5,7) ......> rotation 180° about the origin ........> (5,-7)
Based on the above, all you have to do to get the coordinates of C' is change the signs of both the x and y coordinates
Hope this helps :)
