Answer:
The required co-ordinate is (-2, -5).
Step-by-step explanation:
For a given point, reflection of a point (x, y) across a horizontal line y = k, the reflected co-ordinates will be:  .
.
Here, (x, y) = (-2, 7) then reflection along the line y = 1, we get:

= (-2, -5)
The reflected point is (-2, -5).
 
        
             
        
        
        
Answer:
a= 168
p= 62
Step-by-step explanation:
25 24 and 7 are pythagorean triples. meaning the short side length is 7.
24*7 = 168
48+14=62

Answer: y + 2 =  ( x - 4 )
 ( x - 4 )
Step-by-step explanation:
The equation of a line in point - slope form is given as ;
y -  = m (x -
 = m (x -   )
)
 = 4
 = 4
 = -2
 = -2
m = 
Substitute the values into the equation , we have
y - (-2) =  ( x - 4 )
( x - 4 )
y + 2 =  ( x - 4 )
 ( x - 4 )
Which could be written as :
y + 2 = y + 2 =  x + 2
 x + 2
 
        
             
        
        
        
It will be a negative.
for an example: -20 for x would mqke 2x + 1 into -39 and 8x + 5 into -155. that's 116 apart, so maybe -2(8) + 5 = -11
-2(2) + 1 = -3
but that's only 8 apart, so it'd be higher.
-4(2) + 1 = -7
-4(8) + 5 = -27
BOOM
Tadaaaa, 
You probably thought positive, but sometimes it's negative, you know what I mean?
