Solve each equation by graphing.
The solution of equation is .
A linear function is a function whose graph is a straight line. The solution or root of an equation is any value that makes the equation true. A linear equation has at most one root. Root of an equation can be calculated by graphing the related function. To write the related function for an equation, replace 0 with .
Since the equation is given to be ,
therefore, its related function will be . To graph the function, make a table.
Graph the equation by plotting the values from the table and get:
The graph intersects the x-axis at . So, the solution is .
