Finding Intercepts of Linear Equations

This lesson covers solving linear equations by finding the x and y-intercepts of a graph. It explains the process of setting x or y to zero to find the intercepts and discusses the importance of understanding the signs in equations. The lesson also compares the slope-intercept and standard forms of equations, highlighting their uses in finding intercepts and slopes.
