Step-by-step explanation:
well, the translation (x+6, y+1) creates the following points :
D goes from (-4,-4) to (2,-3)
E goes from (-4,-2) to (2,-1)
A good from (-1,-4) to (5,-3)
the reflection over the x-axis leaves then the x values unchanged, and negative y values turn positive (or vice versa, if we had a case here).
so,
D' = (2,3)
E' = (2,1)
A' = (5,3)
24x-45y=34x
To solve for y, subtract 24x:
-45y=10x
Divide by -45:
y=-10/45x
Reduce:
y=-2/9x
To solve for x, subtract 24x:
-45y=10x
Divide by 10:
-45/10y=x
Reduce:
-9/2y=x
