Finding the Intercepts of a Linear Equation
The intercepts of a linear equation can be determined algebraically by exploiting the fact that one coordinate is always zero at each intercept.
- Finding the -intercept: Substitute into the equation and solve the resulting equation for . The solution gives the ordered pair .
- Finding the -intercept: Substitute into the equation and solve for . The solution gives the ordered pair .
