The dietitian informed Sami, if she follows the plan, her results should be in alignment with the following linear model. In this model, x represents the number of weeks on the plan, and y represents Sami's weight (in pounds). Interpret the y-intercept

    the y-intercept, is the weight y at x=0, so we have: y-intercept = 342-2.2*0= 342 Namely the y-intercept is the weight at the starting of the plan

    since the quantity x measures the number of weeks of the plan, then we have that at x=0, namely at the week number zero, the weight is: y=342- 2.2* 0= 342-0= 342
