It is the linear equation of a straight line.
The question contains two equations:5x - 6y = 15 5x + y = 2 There are no inequalities in the question.
A linear equation is of the form y=mx+c, where m and c are constants. Therefore, y=5x is a linear equation. Here m=5 and c=0.

5x-y equals 18 = -13
3X = 5Y solve for Y Y = 3/5X this is by definition a linear equation solved. You can plat this straight line on a graph.
If y equals 5x-15 and x equals 1 then the value of y comes out to be -10. So y equals 5x-15 is -10.
It is a linear function passing through the origin. It represents a direct proportionality between x and y.
