Answer:
y = 9x -83
Step-by-step explanation:
Parallel lines will have the same slopes but different b values so we know that the base of this equation will be
y = 9x +b
To find b we must plus in the given coordinates and determine which value of b makes the statement true.
16 = 9(11) + b
16 = 99 + b
b = -83
Therefore the new equation will be:
y = 9x -83 or y-16 = 9(x-11)
Answer:
20 cm^2
Explanation:
Degree of area you want to find: 80
Length of radius: 9
Equation: 80/360 times 9
80/360= .2222222...
.2222222... times 9 = 20
So the answer is 20 cm^2
