Alinear function that represents the number of video games purchased at an electronics store is compared to a different linear function that represents the amount of money the store made that day. describe the key features of the functions that are needed to determine if these lines intersect.

Let total number of video games purchased from electronics store = m

 So,→ x=m,or y=m, Represents linear equation which represents number of video games purchased.(1)

For purchasing, m video games ,let amount of money spent is given by

     →y=mx, x is amount of money spent on buying a single video game.

                         (2)

Equating (1) and (2)

→One line is Passing through origin and another line cuts either x axis at (m,0) or y axis at point (0,m).

So, there will be one point of Intersection of these two intersecting lines.

If all variables represent real numbers you can graph the equation by plotting enough points to recognize a pattern and then connect the points to include all points.

Step-by-step explanation:

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'.
