<em>(x, y) --> (-x , y)</em>

Step-by-step explanation:

When reflecting across the y-axis, you will want to switch the sign of the x-coordinate. If the x-coordinate is positive, you will want to switch it to negative and vice versa.

Examples:

(3,5) --> (-3,5)

(-6,-2) --> (6,-2)

~

If you are going to reflect across the x-axis, you will change the y-coordinate, so it is the opposite of reflecting across the y-axis.

Answer: (x, y) —> (-x, y)

Step-by-step explanation:

This is because the translation rule for reflection across the y-axis is (x, y) —> (-x, y)

Solve for y. -13=4y+3
mina [271]

Answer:

y = -4

Explanation:

The initial expression is:

-13 = 4y + 3

So, we need to substract 3 from both sides of the equation:

-13 - 3 = 4y + 3 - 3

-16 = 4y

Then, dividing both sides by 4, we get:

-16/4 = 4y/4

-4 = y

Therefore, the solution of the system is y = - 4.
