The vertices of the reflection of the triangle over the line y = x is graphed at the end of the answer.
<h3>What is the rule for a reflection over the line y = x?</h3>The rule for a reflection over the line y = x is given by:
(x,y) -> (y,x).
Hence we apply the rule to each vertex of the original figure to find the vertices of the reflected figure.
The vertices of the original triangle are:
(-1,1), (-3,1) and (-1,4).
After the reflection over the line y = x, the vertices will be given as follows:
(1, -1), (1, -3), (4, -1).
We just exchanged the x and y coordinates from the original vertices.
The original triangle, the reflected triangle, and the line are graphed at the end of the answer.

Answer:
it is application of the multiplication property of equality
Step-by-step explanation:
You can use "cross products" to solve any proportion. What looks like a "cross product" is just application of the multiplication property of equality. That property says the variable value is unchanged if both sides of the equation are multiplied by the same value.
For your fraction, the "cross product" is what you get when you multiply both sides of the equation by 500.

Note that the next step here is to divide by the x-coefficient, the 5 that was in the left-side denominator.
Please also note that this is exactly the same result you would get by multiplying the original equation by the original denominator of x.
