Shane says that the equation for the table of values is,

 $y=-x+2$  , describe and correct the error.

• Shane has the wrong slope and y-intercept; the answer should be  $y=\frac{1}{2}x-1$  

• Shane forgot to write a number for the slope, the correct answer is  $y=-1x+2$  

• Shane accidentally substituted the values into the equation wrong, the correct answer is  $y=2x-1$  

• Shane wrote the equation wrong, the correct answer is  $y=-x2$
