Finding x-intercepts & y-intercepts

 

 

Make a table with a 0 for x & a 0 for y.  Substitute 0 for x to find the y-intercept.  Substitute 0 for y to find the x-intercept.

 

 

Ex:  Find the intercepts for 3x + 2y = 6.  

 x

                                                         3∙0 + 2y = 6     y = 3        

                                                                   

                                                                   3x + 2∙0 = 6     x = 2
