Answer:

y=8x, \\y=12x

Step-by-step explanation:

Proportional functions can be written as y=kx, where k is some constant of proportional. Since directly proportional functions always pass through the origin, the y-intercept must be 0 (no additional number before or after x term). The only answers that fit this format are:

\rightarrow \boxed{y=8x}\\\rightarrow \boxed{y=12x}

Rectangle RSTU and the image R’S’T’U’ are graphed on the coordinate grid below.
Ksju [112]

The rectangle  R’S’T’U’ is a 90° counterclockwise rotation of RSTU so options (A) and (C) will be correct.

<h3>What is a rectangle?</h3>

The rectangle is a geometrical figure in which opposite sides are equal.

The angle between any two consecutive sides will be 90 degrees.

Area of rectangle = length × width.

Perimeter of rectangle = 2( length + width).

Given the rectangle RSTU if we plot it then it becomes a major horizontal rectangle.

If we transpose into R’S’T’U’ then it rotates 90 degrees counterclockwise and becomes a major vertical ractangle.

Hence the rectangle RSTU will rotate 90° counterclockwise to form  R’S’T’U’.
