For -(4)^7
the - is not affected by the power of 7

For (-4)to the power of7 is the same as -4 to the power of 7

It is because 7 is an odd number,the - will not change .Therefore
(-4)^7= -(4)^7

But keep in mind that if the power is an even number , the - will change to + when the situation is (-4)
For example,(-4)^4=(4)^4

I am not good at English if there is any things that you feel confused you may ask

Through (4,-4) ; perpendicular to 6y=x-12
BARSIC [14]

y = mx + b

m = slope and b = y-intercept


We can arrange 6y = x - 12 in the form of y = mx + b

                  6y = x - 12

                    y = 1/6(x) - 2

Slope of y = 1/6(x) - 2 is 1/6. Taking the negative reciprocal of the slope we get the slope for the perpendicular line.

Negative reciprocal of 1/6 is -6.

The equation for the perpendicular line is

                  y = -6x + b

To find b we can plug in the x and y values of (4,-4) into it since it passes through those coordinates

                -4 = -6(4) + b

                 b = -4 + 6(4)

                 b = -4 + 24

                 b = 20

So the equation for the perpendicular line is y = -6x + 20
