Answer:

1. (4,6)

2. (-1, 8)

3. Not enough information given.

Step-by-step explanation:

1. Reflecting the point over the y-axis will place the point (-4,6) 4 units on the other side of the axis. This would place it at (4,6) without changing the y-coordinate.

2. Reflections across the line y=x means y and x trade places. This will result in the point (8,-1) becoming (-1,8).

3. Not enough information about the shape is given. Need to know where it is now to know where it will go.

Solve the system of equations using the substitution method.

Delicious77 [7]

Answer:

$x = 14$

$y = -3$

Step-by-step explanation:

Given

$2x + 8y =4$

$x = -3y + 5$

Required

Solve

Substitute $x = -3y + 5$ in $2x + 8y =4$

$2(-3y + 5) + 8y =4$

Open bracket

$-6y + 10 + 8y =4$

Collect like terms

$-6y + 8y =4-10$

$2y =-6$

Divide both sides by 2

$y = -3$

Substitute $y = -3$ in $x = -3y + 5$

$x = -3 * -3 + 5$

$x = 9+ 5$

$x = 14$
