First, you find m by doing . You end up with . Then you plug it intoto find the <em>b</em> in . When you do that, you get . So, you end up with the equation of the table asand since it's a linear function, the slope (<em>m</em>) won't change. Now you compare this equation to the others given. The slope in answer <em>A</em> is too small and the y-intercepts in answers <em>B</em> and <em>C</em> are too small, so you are left with b as your only option.
