deviation of $14. Construct and interpret a 99% confidence interval for the mean amount of money spent per month on home
maintenance by all homeowners.

Y = 1/2x - 3. Slope here is 1/2. A perpendicular line will have a negative reciprocal slope. All that means is flip the slope and change the sign. So the perpendicular line will have a slope of -2.
y = mx + b
slope(m) = -2
(1,-1)...x = 1 and y = -1
now we sub and find b, the y int
-1 = -2(1) + b
-1 = -2 + b
-1 + 2 = b
1 = b
so ur perpendicular equation is : y = -2x + 1
Okay and what do you need to find??
Answer:
Step-by-step explanation:
It's about 2.064 if you make the number an improper fraction then divide
