I’m pretty sure it’s y=-4x-16
Because the standard slope equation is y=mx+b and in perpendicular lines the slope is opposite of the slope on a parallel line. 0.25 is equal to 1/4 and the opposite of 1/4 is 4/1 but you also make it negative so it’s -4. So we have y=-4x+b and you plug in the coordinates and solve [8=-4(-6)+b and -4*-6=24 so you rewrite it as 8=24+b and 8-24=-16 and -16=b] so you plug in b and the equation is y=-4x-16
Hope this helped
Answer: 1.467
Step-by-step explanation:
Formula of Margin of Error for (n<30):-

Given : Sample size : n= 22
Level of confidence = 0.90
Significance level : 
By using the t-distribution table ,
Critical value : 
Standard deviation: 
Then, we have

Hence, the margin of error for the confidence interval for the population mean with a 90% confidence level =1.467
