The linear equation:
y = k x + b
We will use first two values and solve the system of equations:
11 = k * 7 + b / *(-1)
13 = k * 8 + b
---------------------
-11 = - k * 7 - b
13 = k * 8 + b
----------------------
2 = k
13 = 16 + b
b = 13 - 16 = -3
y = 2 x - 3 ( y varies directly with x )
Answer: y - 9 = 2(x - 5)
Step-by-step explanation:
Point slope form: y - y1 = m(x - x1)
substitute 5 for x1 and 9 for y1 and 2 for m
x1 = 5
y1 = 9
m = 2
you get y - 9 = 2(x - 5)
Either way you go 180 degrees clockwise or counter clockwise it will land in the same spot
Answer:
6.7 inches
Step-by-step explanation:
the statue is 67 feet tall, and in the replica, every inch is 10 feet. All you would need to do is move the decimal point to the left by one point.
Linear fonction's equation : y = ax
So only in y = 2x
