What is the equation of the line described below written in slope-intercept form the line passing through the point (-1,5) and parallel to the line whose equation is x + y = 10y=x-4
y=x+4
y=-x+4​

Answers

Answer 1
Answer:

The correct answer is y=-x+4​

Further explanation:

Given equation of line is:

x+y = 10

Comparing it with the standard point-slope form

y = mx+b

We get

y = -x+10

So

m = -1

As the new line is parallel to given line it will also have m=-1 as slope of two parallel lines is equal

For finding b, we will put the point and value of m in standard form

y = mx+b\n5 = (-1)(-1) + b\n5 = 1+b\n5-1 = b\nb=4

Hence the equation will be:

y = (-1)x+4\ny = -x+4

The correct answer is y=-x+4​

Robert is using the following data samples to make a claim about the house values in his neighborhood:House Value
A $250,000
B $275,000
C $300,000
D $267,000
E $250,000


Based on the data, should Robert use the mean or the median to make an inference about the house values in his neighborhood?
He should use the mean because it is in the center of the data.
He should use the median because it is in the center of the data.
He should use the median because there is an outlier that affects the mean.
He should use the mean because there are no outliers that affect the mean.

Answers

Both mean and median are measures of the center of a set of data.
Mean is normally preffered to the median except if there is an outlier that has a tendency to affect the mean.
An outlier is a data point that significantly differs from the other data points in a sample.
In the data set above, there is no outlier that will affect the mean.
Therefore, he should use the mean because there are no outliers that affect the mean.

(30/ If the surface of a lake represents a plane, what geometricterm is represented by the intersection of a fishing line
and the lake's surface?

Answers

Answer:

  • A point

Explanation:

The surface of a lake represents a plane because it extends in all directions at the same level. Imagine it as a quite surface, without imperfections, smooth and perfectly plane, it is a two-dimensional figure.

A fishing line that enters into the water, crossing the lake's surface, representes a line, which may be either perpendicular or leaned.

Thus the intersection of those two figures is a point.

A surface and a line that is not included in the plane and is not parallel to it will meet at a single point, which is what is represented by the situation stated.

Answer:

The geometric term that is represented is

a point.
