Given two points $A = (A_x, A_y),\ B = (B_x,B_y)$ , the slope of the line passing through the two points is

$m = \dfrac{A_y-B_y}{A_x-B_x}$

So, in your case, you have

$m = \dfrac{3-5}{-2-4} = \dfrac{-2}{-6} = \dfrac{1}{3}$

Answer:

Step-by-step explanation:

Total Work hours = 3 1/2 hours

One routine physical routine requires: 1/3 hours.

Number of routines can be completed = Total work hours / Time required for one physical routine

= $3\frac{1}{2} / \frac{1}{3}\\=\frac{7}{2} /\frac{1}{3} \\=\frac{7}{2} *3\\$

= 10.5 routines.

In this case, we are unable to complete half a routine (0.5), so we will choose the highest possible whole number, in this case, its 10 routines.
