The perpendicular bisector is a line segment that is drawn from a vertex of an angle to the midpoint of another line segment creating a right triangle or a 90° angle in the process. Suppose AB is the base segment of the triangle, therefore the perpendicular sector is also the angle bisector of the other angle of the triangle, supposedly angle C. Angle bisector is a line segment that divides the angle into two equal parts. Imagine a line drawn from the top vertex C extended down to the midpoint of line AB. That is the perpendicular and angle bisector.

Given the following information, write the equation of the line in slope-intercept form. Slope = -8 and y-intercept = 4
Montano1993 [528]

Answer:

y = -8x + 4

Step-by-step explanation:

Using the y = mx +b for the slope intercept form, the m stands for the slope and the b stands for the y-intercept.

In this case, the slope is -8 and the y-int is 4 so we naturally plug those in

If we consider the simple random sampling process as an experiment, the sample mean is a. a random variable. b. always zero. c.
marta [7]

The sample mean is an estimate of the population mean.

The sample mean is exactly equal to the population mean

<h3>How to determine the true statement</h3>

When the population mean is known; the value of the population mean can be used as the sample mean.

This is so because:

The sample mean is an estimate of the population mean.

And it is represented as:

\bar x = \mu

Hence, the true statement is that the sample mean is exactly equal to the population mean

What is the equation of the line that passes through the point (-2, 7) and has a slope of zero
lorasvet [3.4K]

Answer:

y = 7 is the equation of the line that passes through the point ( -2, 7 ) and has a slope of zero.

Step-by-step explanation:

Given:

Let,

A ≡ ( x1 , y1 ) ≡ ( -2, 7 )

Slope = m = 0

To Find :

Equation of Line:

Solution:

Formula for , equation of a line passing through a point (  x1 , y1 ) and having a slope m is given by

(y - y_{1})=m(x-x_{1})

Now substituting the values of x1 = -2 and y1 = 7 and slope m = 0 we get,

y-7=0\times(x--2) \\y-7=0\times (x+2)\\y-7=0\\\therefore y=7

Which is the required equation of a line passing through the point ( -2, 7 ) and slope zero
