y = -2

Step-by-step explanation:

The y value is -2

The line is a horizontal line

Horizontal lines are of the form

y = -2

y = -2

Step-by-step explanation:

When it comes to the lines you have to think opposite for the y and x since the line is horizontal which tends to make you think x axis you must remember that it would be y = -2 not x = -2.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
