Hello!
To find slope, calculate the change in y-values and divide it by the change in x-values:
y1 - y2 / x1 - x2
You have the coordinates (-4, 5), (0, 6), and (8, 8). You can use any combination of two of these points to calculate slope. I'll use (0, 6) and (8, 8).
6 - 8 / 0 - 8
-2 / -8
1/4
Answer:
The slope of the line is 1/4
Special prpoerty of 45-45-90 triangle
if the legs are x then the hyptonuse is x√2
18=hyptonuse=x√2
18=x√2
divide both sides by √2
18/√2

times by √2/√2
(18√2)/(2)

one leg is 9√2 cm
Answer:
70 clicks in 20 seconds
Step-by-step explanation:
The speed of the train in mile per hour is approximately the number of clicks heads in 20 seconds.
Each click shows that the train has travelled 30ft
1 click per second is =(30ft/sec = 3600 × 30) / 5280
20.45mph approximately 20mph
Therefore
20mph = 20 clicks in 20 s
30mph = 30 clicks in 20s
70mph= 70 clicks in 20s
