To find slope, use the formula:
(y2-y1)/x2-x1)
So here is what it will look like:
(9--7)/(1--3)
Since you are subtracting a negative, then it turns unto a positive so you are adding the numbers together.
(9+7)/1+3)
16/4
4
The slope of the line is 4/1 or 4. Which means that you will go up or "rise" 4 and go to the left or "run" 1.
Hope this helps!
Answer:
28.26 
Step-by-step explanation:
The radius is half of the diameter. 6/2 = 3, so the radius of this circle is 3 cm.
The formula for the area of a circle is: π
Plugging 3 into the radius, we have:
× π =
9 × π
We can round π to 3.14
9 × 3.14 = 28.26

Answer:
Step-by-step explanation:
$ 8 admission and $ 2 a ride
y = 2x + 8.....where y is the total cost and x is the # of rides
table :
x = 1 , 2 , 3 , 4 ,5 , 6
y = 10, 12 , 14, 16 , 18 , 20
