The graphs of the two equations have only one intersection point.
There is no special name. Two totally unrelated equations could have the same solution(s).

Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
equal equations.
The solution of a system of linear equations is a pair of values that make both of the equations true.
The two equations represent parallel lines.
If you graph the two functions defined by the two equations of the system, and their graphs are two parallel line, then the system has no solution (there is not a point of intersection).
The graphs of the two equations have only one intersection point.
The slopes (gradients) of the two equations are different.
There is no special name. Two totally unrelated equations could have the same solution(s).
Consistent equations are two or more equations that have the same solution.

Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
A system of equations will have no solutions if the line they represent are parallel. Remember that the solution of a system of equations is physically represented by the intersection point of the two lines. If the lines don't intersect (parallel) then there can be no solution.
