Linear Equations & Linear Systems:Question 1 David is solving a system of linear equations by
graphing. First, he graphed both equations on a
coordinate plane. What should be his next step in
solving the system of linear equations?
Select one:
find the measure of the angles where the lines intersect
find the x-intercept of each line
find the location of the point where the lines intersect
find the y-intercept of each line

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'.

imma say 16%. sorry if its wrong. i'm doing the same stuff right now
