Answer:
below
Step-by-step explanation:
1)
y = -2x/3 - 4
m = 2x/3
b= 4
2)
y= -x +2
m= -1
b = +2
3)
y= -x-2
m = -1
b =-2
Answer:
4/5
Step-by-step explanation:
In a right triangle such as this one
cos (angle) = adjacent leg / hypotenuse
cos(k) = KL / 15
You will need to find the leg length KL using Pythagorean Theorem
15^2 = 9^2 + (KL)^2 KL = 12
then cos k = 12/15 = 4/5
If the number is big enough there can be up to an infinite number of decimals
