possible answers:
1. y = 2
2 3x + y = 1
3. 3x + y = −1

4.

Step-by-step explanation:

Quadrilateral ABCD is a square. A square can be reflected onto itself across its diagonals.

Find the equation of the diagonal AC. This diagonal passes through the points A(-3,0) and C(-1,2). Hence, the slope of the line AC is

Thus, the equation of AC is

20

step-by-step explanation:

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
