Answer:
(1, -2) Option A in your list of possible answers
See attached image.
Step-by-step explanation:
We need to graph the lines by using a couple of points on the plane for each equation.
For example:
the points (0, -3) and (3, 0) for the line y = x - 3
and the points (0, 1) and (-1, 4) for the line y = - 3 x + 1
Please see the lines in the attached image, and notice that they intersect at the point (1, -2), which gives you the solution for the system.
Since triangles ABC and BCD are similar, we can establish a proportion between the lengths of corresponding sides:
We can infer from our picture that
. Also we can find the length of AC by adding AD and CD:
Lets replace the values in our proportion:
Solving for
:
We can conclude that the correct answer is: D
