Nezavi [6.7K]

His co-payment for his physician visits would be:

10 x 18 = $180.

His co-payment for his physical therapy would be:

10 x 20% x 150= $300.

You then have to add both co-payments which give you $480.

Find the slope of the line through<br> (-11,8),(-11, -17)

Rom4ik [11]

Answer:

Undefined or Infinity

Step-by-step explanation:

(x1,y1)=(-11,8)

(x2,y2)=(-11,-17)

Slope = (y2-y1)/(x2-x1)

= (-17-8)/(-11-(-11))

= -25/0

= Undefined
