he intercept for a straight line is 12. If the value of the independent variable is 3, then the value of the dependent variable would be 18. The slope of this line is

2

Step-by-step explanation:

The equation of a line is given as

y = mx + c where m is the slope, c is the intercept, y is the dependent variable while x is the independent variable.

As such, given that the intercept is 12, the independent variable is 3 and the value of the dependent variable would be 18

substituting into the equation of a line

18 = m(3) + 12

subtract 12 from both sides

18 - 12 = 3m

6 = 3m

Divide both sides by 3

6/3 = 3m/3

2 = m

m = 2

The slope is 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.

well what you have to do is divide 84 by 6 so theanswer

step-by-step explanation:

84 divided by 6 = 14

and that lightbulb changing party must be freaking lit!
