Question

Solve the following system of linear equations graphically:
4x-5y-20=0
3x+5y-15=0
Determine the vertices of the triangle formed by the lines representing the above equation and the y-axis.

Answer 1

The given system of equation is

Thus, we have the following table:

Graph of the given system of equations:

Clearly, the two lines intersect at 4(5, 0) , Hence, 5, x-5, y-0  is the solution of the given system of equations.
