J(x)=67x
so if it was j(1)=67(1)
so j(15)=67 x 15= 1005
you can do 1005 jumping jacks in 15 minutes

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (look at the picture) (0, 1) and (-2, -2). Substitute:

$m=\dfrac{-2-1}{-2-0}=\dfrac{-3}{-2}=\boxed{\dfrac{3}{2}}\to\boxed{D}$
