Will make brainliest if answer correctly

Rule A (x, y) → (x, -y) describes the transformation.

Step-by-step explanation:

Step 1; To understand reflection across an axis we need to be able to know which quadrant the shape is already in and in which quadrant it will be in after reflection. The given shape is currently in the fourth quadrant where the points in it will have a positive x coordinate and a negative y coordinate. So assume the values are in the format of (x, y).

Step 2; Due to reflection across the x-axis, the shape will be reflected in the first quadrant. In this, the x and y coordinates both have a positive value. So due to reflection, the x value remains unchanged while the y value is the same but it has the opposite symbol i.e. negative. So if the shape had a value of (x, y) due to reflection it would have (x, -y).

y - y1 = m(x- x1)

y - (-5) = 2/3(x -0)

y + 5 = 2/3x

y = 2/3x - 5

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
