(15 points and brainliest) sorry for the poor quality the function graphed shows the total cost of a gym membership for x months. identify the gym membership information provided by the graph. the slope is a. 15 b. 10 c. 1.5 d. 1 the slope represents a. the total cost of the membership b. the starting fee c. the monthly cost of the membership d. the number of months as a member

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

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.
