To find out if the point lies on the line described by the equation , we can rearrange the equation into slope-intercept form and substitute the and values of the point into the equation. The line can be expressed as . When we substitute , we get . Since does not equal , the point does not lie on the line.

Additionally, if you want to check whether a point lies on a line defined by a linear equation, simply plug the coordinates into the equation. A common mistake is forgetting to maintain the signs or miscalculating the multiplication. Double-checking your calculations can save you from such pitfalls!
