Answer 1

well, the table has 5 points in it, let's pick any two hmmm say let's use hmmm (2 , 7) and (6 , 17)

`(\stackrel{x_1}{2}~,~\stackrel{y_1}{7})\qquad (\stackrel{x_2}{6}~,~\stackrel{y_2}{17}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{17}-\stackrel{y1}{7}}}{\underset{run} {\underset{x_2}{6}-\underset{x_1}{2}}}\implies \cfrac{10}{4}\implies \cfrac{5}{2}`

when x = 0, from the table, y = 2, so there's the y-intercept.
