The answer would be y = 2x-16

Okay so a perpendicular line has a slope of the opposite reciprocal so for example in this equation the slope is 2 so the slope of a perpendicular equation would be -1/2 now since you know that you can put that in the slope intercept equation
Now you have y=-1/2x+b and since you have a point (point A) you can plug it in and solve for b
-8=-1/2(4)+b
-8=-2+b
b=-6
Now you have both parts simply put it in and you have the equation
y=-1/2x-6
I also attached the image with both to prove they are perpendicular

What needs to be corrected in this construction of a line parallel to line AB passing through C?
UNO [17]

The option that needs to be corrected in this construction of a line parallel to line AB passing through C is C: the second arc should be centered at C.

<h3>Why should the second arc be centered at C?</h3>

The second arc should be centered at C because as it crosses passing through Line C, it is seen that it was not touching or intersecting AB and so one can say that it is parallel to it.

Looking at the other lines, we will see that they are all touching AB and are not running parallel to it.

Hence, The option that needs to be corrected in this construction of a line parallel to line AB passing through C is C: the second arc should be centered at C.

This is the digit that tells you whether to round up or down
Arte-miy333 [17]

When you want to round up or down numbers focus on only two digits,which is the digit in place that you are rounding to and the digit to it's immediate right which tells you whether to round up or down.When the number you are rounding is between 0-4, you round down to the next lowest number. When the number is 5-9,you round the number up to the next highest number.

For example: If you have 25 and you want to round it up then it will be rounded up to 3 because 5 can be rounded up to the next number which is 2 to make it 3.But when you have 23,then you can't round it up which means you will have to round it down to 20 since the 3 behind the 2 can't round up.

I hope this helps......
