What is the slope of the line through (2,-2)(2,− 2, comma, minus, 2, )and (9,3)(9, 9, comma, 3, )? choose 1 choose 1

a.(choice a) a \dfrac57 7 5 start fraction, 5, divided by, 7, end fraction
b.(choice b) b -\dfrac75− 5 7 minus, start fraction, 7, divided by, 5, end fraction
c.(choice c) c -\dfrac57− 7 5 minus, start fraction, 5, divided by, 7, end fraction
d.(choice d) d \dfrac75 5 7

A)  

Step-by-step explanation:

Use the two-points formula for the slope of a line.

We know that the points (2,-2) and (9,3) are on the line. If (a,b),(c,d) are points on a line then the slope m is defined by the equation . In this case, a=2,b=-2,c=9 and d=3 then the slope is .

C. 1004.8  cubic units

Step-by-step explanation:

Lets analyze the problem given, we have to find the volume of cylinder and use 3.14 as pi.

We can use the formula V=(3.14)r^2h to find the volume of the cylinder.

Below is the work to solve the formula:

8^2= 64

64(5)=320

320(3.14)=

1004.8  cubic units is our answer.
