Identify the coordinates of four points on the line with each given slope and y-intercept. slope= 1.5, y-intercept= -3

The slope-intercept form:

m - slope

b - y-intercept

We have the slope = 1.5 and y-intercept b = -3. Substitute:

Choose any value of x and calculate y:

for x = -2

for x = -1

for x = 0

for x = 1

for x=2

step-by-step explanation:

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.
