y=4x+(-9)

Step-by-step explanation:

Slope intercept form is y=mx+b

m is the slope which can be found using rise/run. In this case 4/1=4 so m=4

b is the y intercept which is the y value where the line passes through the X axis. This also can be found as the Y value where X=0 if that is easier for you. In this problem y=-9 where X=0. Therefore b=-9.

Plug these values back into the equation and you get the equation of the line in slope intercept form. For this line that is y=4x+(-9).

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.

we have the parent function given by,

1. the function is translated 5 units to the left.

so, we get,   becomes

2. the function is translated 5 units to the right.

so, we get,   becomes

3. the function is translated 5 units upwards.

so, we get,   becomes

4. the function is translated 5 units downwards.

so, we get,   becomes

5. the function is reflected across x-axis.

so, we get,   becomes

6. the function is reflected across y-axis.

so, we get,   becomes .
