Because it is a rhombus (all equal sides), then the following relationship exists between the angles

Considering triangle RSU.

This gives:




<em></em>
<em> --- Opposite angle of a rhombus</em>
The system of equations does not have one solution because the lines will never intersect (last one)
Answer:
y+1=(x+7)/3
Step-by-step explanation:
slope = (-1-3)/(-7-5) = -4/-12 = 1/3
b = 3-(1/3)×5 = 4/3
y = mx+b
or, y = x/3+4/3
its point slope form,
y = x/3+4/3
or, y=(x+4)/3
or, y+1=(x+4)/3+1
or, y+1=(x+4+3)/7
or, y+1 =(x+7)/3
M(2,-4), N(-2,4)
