Question

a system 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.

Answer 1

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)
