(a) Find the slope of the line connecting the point $(7,30)$ to the point $(12,60)$ .
Slope = help (numbers)

(b) Find the slope of the line connecting the point $(7,30)$ to the point $(17,90)$ .
Slope = help (numbers)

(c) Find the slope of the line connecting the point $(7,30)$ to the point $(22,120)$ .
Slope = help (numbers)

(d) Could the table below represent a linear function?

$x$	$y$
7	30
12	60
17	90
22	120

(e) If the table could represent a linear function, give a formula for the linear function. If it is not a linear function, enter NONE.
$y =$ help (formulas)
