What would Y and x be classified as and is this written correctly

Is a line an appropriate model for these data? Justify your answer (use information given in question 1) ' yes VI there is no pattern in the residual plot V' Alana's favorite exercise machine is a stair climber. On the -randomll setting, it changes speeds at regular intervals, so the total number of simulated -floorsll she climbs varies from session to session. She also exercises for different lengths of time each session. She decides o explore the relationship between the number of minutes she works out on the stair climber and the number of floors it tells her that she's climbed. She records minutes of climbing ime and number of floors climbed for six exercise sessions. Computer output and a residual plot from a linear regression analysis of the data are shown below.
