Answer:
y=-9x-1
Step-by-step explanation:
since it is perpendicular, the slope must be the opposite reciprocal (-9x) and now we plug the coordinates in, -1=0+b, b is -1
Step-by-step explanation:

I hope it makes sense

Answer:
x = 14
Step-by-step explanation:
Step 1: First, Simplify the fraction.

Step 2: Next, Multiply both sides by 7.
4x = 8 × 7
Step 3: Simplify 8 × 7 to 56.
4x = 56
Step 4: Then, Divide both sides by 4.

Step 5: Lastly, Simplify the fraction and you're done!
x = 14
6z-7z/5=3
(30z-7z)/5=3
30z-7z=15
23z=15
z=15/23
<span>Answer: Skewed to right with mean 0 and S.D. 1
Explanation: Let's assume the z-scores as a linear transformation.
then z=(x-mean)/S.D. = (x-30)/15
z(mean) = (30-30)/15= 0
z(sigma) = 15/15 = 1
