E) Quadrilateral WWXY if V(0, -1), W(1, 1), X(4,-1), and Y(1,-5)
reflected over the line y = -x.

V'(1, 0),W'(-1, -1), X'(1,-4), and Y'(5,-1)

Step-by-step explanation:

(x,y) --> (-y,-x)

21

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
