1. (-4,5) (3,-5)
In slope intercept form

2. (-3,4) (-2,-2)
Slope intercept form

Step-by-step explanation:

first use the formula box slope m then use y intercept equestion

step-by-step explan mxfcg'k; uafwgzfgjhklhgation:

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.
