Answer:
y - Q = -5/2(x - P)
Step-by-step explanation:
The equation of a line in point slope form is expressed as y - y0 = m(x-x0)
(x0, y0) is the point
m is the slope
Given the equation
y = 2/5x− 4.
Slope m = 2/5
Slope of the perpendicular line = -1/(2/5) = -5/2
Point;
x0 = P
y0 = Q
Substitute into the formula;
y - y0 = m(x-x0)
y - Q = -5/2(x - P)
This gives the required equation

Answer: 170
Step-by-step explanation: 170x90% (0.9) = 153
So, if k/9=3/9, then k=3, because it is a variable substituting 3. :D Hope I could help!
I am not sure, but I think you are talking about the least square method
