Asystem of linear equations include the line that is created by the equation y=0.5x-1 and the linethrough the points (3, 1) and (–5, –7), shown below.

The complete question in the attached figure

we know that

the intersection of both graphs is the solution of the system

we have that
y=0.5x-1 
and
the line through the points (3, 1) and (–5, –7)

using a graph tool
see the attached figure

the solution is the point (2,0)

Dwould be the answer
