Me i will give brainliest i need to answer all of these and explain them

31. The slope of y = 8x - 1 is 8. So a line perp. Would have a slope of -1/8
So to find the equation of the new line, we use
y= mx + b
10 = (-1/8)(4) + b
10 = -1/2 +b
+1/2. +1/2
10 1/2 = b

New Equation: y = (-1/8)x + 10 1/2

32. Negative correlation ( it looks like the data generally is going from top left to bottom right)
33. No correlation
34. Positive correlation (it looks like the data is generally going from bottom left to top right.

All you have to do is multiply
