Which of the following is an equation of the line, in point slope form, that passes through the points (9,1) and (4,16)?

y=-3x+28

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(16-1)/(4-9)

m=15/-5

m=-3

y-y1=m(x-x1)

y-1=-3(x-9)

y-1=-3x+27

y=-3x+27+1

y=-3x+28

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

the answer is thin because within context, the stanza concludes the and frail tone the people have toward each other, and the fact that it would be thin, makes the most sense compared to "pliable" or "not hard or firm to the touch". hope this , good luck.
