They are (0,6) because if the center of dilation is point A which means it does not change, while both other points increase their distance from point A by a factor of two (double)

write the point-slope form of the line that passes through (1,-5) and is parallel to a line with a slope of 1. include all your
Marina86 [1]

<u>Answer: </u>

The point-slope form of the line that passes through (1,-5) and is parallel to a line with a slope of 1 is y + 5 = x – 1

<u>Solution: </u>

The point slope form of the line that passes through the points \left(x_{1}, y_{1}\right) and parallel to the line with slope “m” is given as  

y-y_{1}=m\left(x-x_{1}\right)  ---- equation 1

Where “m” is the slope of the line. x_{1} and y_{1} are the points that passes through the line.

From question, given that slope “m” = 1  

Given that the line passes through the points (1,-5). Hence we get x_{1}=1 and y_{1}=-5

By substituting the values in eqn 1, we get the point slope form of the line which is parallel to the line having slope 1 can be found out.

y – (-5) = 1(x – 1)

y + 5 = x – 1

hence the point slope form of given line is y + 5 = x – 1

Please help with my math work
lilavasa [31]

Answer: (1) is D because D is a further distance from the rest so it is an outlier (2) Negative because it starts at the top and goes further down (3) No because there are not a lot of dots in one place (4) scatter plots can show and identify other patterns in data and they are important because they show thing that other graphs don't you should care because they show very important information

Step-by-step explanation: (1)outliers are an observation that lies an abnormal distance from other values in a random sample from a population. (2)Positive slopes go up and Negatives slope fall down. (3) clusters are when a lot of dots are in one place. (4)
