x  y = 1  x = x  y  x + 1  =  1 1 y = x  1 Slope = m = 1 y intercept = 1 
2x + y = 8 2x =  2x  y =  2x + 8 Slope = m = 2 y intercept = 8 







= 1 


= 8 


= 0 


= 2 + 8 = 6 


= 2 


= 2 + 8 = 10 


= 2 


=  6 + 8 = 2 

Check: Since the two lines cross at (3,2), the solution is x = 3 and y = 2.Checking these value shows that this answer is correct. Plug these values into the ORIGINAL equations and get a true result. x  y = 1 2x + y = 8 (3)  2 = 1 2(3)+ 2 = 8 1 = 1( check) 6 + 2 =8 8 = 8(check)
