Question 51291
think about the standard form of the linear equations


           y=mx+c  where y & x are variables; m is slope and c is Y intercept

              so  substitude the datas in this equation
                       
                        y=(1/4)x+c
                        2=1/4*9 + c
                        c = 2- (9/4)
                         c = (8-9)/4
                         c = -1/4

              so we get the standard form

                       y=(1/4)x-(1/4)
