if you put the points into the equation y2 - y1/x2 - x1 you'll end up with a zero in the denominator, which indicates a vertical slope. Basically the slope(m) is undefined
It's really easy to tell if your answer is going to be undefined if both the x values are the same (in this case they're both 9)
Answer:

Step-by-step explanation:
<u>Step 1: Convert</u>
Six to the third power times six to the fourth power.



Answer: 
Answer: 18600 feet
Step-by-step explanation:
f(t)=33600-1500t
f(t)=33600-1500(10)
f(t)=33600-15000
f(t)=18600
Area of the trapezoid:

Area of the rectangle:
4.2 x 3.1 = 13.02 cm^2
Area of each quarter circle:

We have two quarter circles:
7.54 + 7.54 = 15.08
41.65 + 13.02 + 15.08 = 69.75 cm^2
