if a point (-2/3,5) is solution to must lie on the line
so, generally speaking, the for a point (a, b) to lie on the line is:

To determine whether a point lie on the line you have to just check whether the coordinates of the point given the equation or . For this what you have to do is : Put the value of the any coordinates of the point and check whether it satisfy the equation or not.

........plug in and ...if you get left side of equation equal to , then (-2/3,5) is solution to





...........it's not a solution
check:
..... write it slope-intercept form
...let see if point lie on a line




now you can plot a point (-2/3,5) and see it does not lie on that line
