If x and y are positive real numbers, which expression is equivalent to the expression below?

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:

it is not that hard all u have to do is plot the graph

step-by-step explanation:

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
