Rational number, because the Square root of 400 is 20, since 20 x itself is 400. Hope this helps!
The line of reflection that would map ABCD onto itself is the line of the diagonal which is -3x + 3y = 9
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
The line of reflection that would map ABCD onto itself is the line of the diagonal. The diagonal passes through A(-3, 0) and C(-1, 2), hence:
y - 0 = [(2 - 0)/(-1-(-3))](x - (-3))
y = x + 3
-x + y = 3
-3x + 3y = 9
