Joni should have multiplied by 1,000.
Answer:
A
Step-by-step explanation:
Find the slope of the perpendicular line.
The slopes are related by the formula
m1 * m2 = - 1
Since m1 is 1/2, m2 must be -2
So far what you have is y = -2x + b
Find the y intercept (b).
The new line goes through (4,1)
x = 4
y = 1
1 = -2(4) + b
1 = - 8 + b
b = 1 + 8
b = 9
The answer is
y = - 2x + 9
