X+ 3y = 12
x = -6y
it is system of equations

Step-by-step explanation:

x+3y=12--(1)

x=-6y--(2)

put (2) in (1)

-6y+3y=12

-3y=12

divide both sides by -3

y=(12/-3)

y=-4

put y=-4 in (1)

x+3(-4)=12

x-12=12

x=12+12

x=24

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
