Answer:
2 by 4 is the answer have a great time
The general equation of line with the slope "m" and passing points (a,b) is :
y - b = m (x -a)
In the given question:
Slope m = -2, passing points (a,b) = (4,-4)
Substitute the value of a = 4, b = -4 in the general equation of line

The equation with the slope -2 and passing points (4,-4) is 2x + y = 4
Answer : 2x + y = 4
77/8= 9.625 and 31/4= 7.75...so 9.625-7.75= 1.875
I believe it's 12=0
Hope I helped! ( Smiles )
I think you just got to plot the points it give you the it will be a reflection
