<span>In the equation of a straight line: y = mx + c, slope is denoted </span>

by the letter m.

$\it -2y = x-1|_{:(-2)} \Rightarrow y = -\dfrac{1}{2}x+\dfrac{1}{2} \Rightarrow m = -\dfrac{1}{2}$ <span>

If the coordinates for C' are (4.5, 4.5), which rule best represents the dilation that was applied to rectangle ABCD to create r

Dmitry_Shevchenko [17]

The dilation of rectangle ABCD to create rectangle A'B'C'D' would change the size of the rectangle

The dilation rule is: (x,y) -> k(x,y)

<h3>How to determine the rule of dilation?</h3>

The coordinates of C' is given as:

C' = (4.5, 4.5)

The coordinate of point C is not given.

So, I will apply a general rule

The general rule of dilation is:

(x,y) -> k(x,y)

Where k represents the scale factor.

Assume that k = 3, the the rule would be
(x,y) -> 3(x,y)

Need help thank you.

Answer:

x = 20

Step-by-step explanation:

The three angles make up a straight line.

A straight line has 180 degrees.

x + 3x + 100 = x80 Combine

4x + 100 = 180 Subtract 100 from both sides

4x = 180 - 100

4x = 80 Divide by 4

x = 80/4

x = 20

A scatter plot contains a trend line that passes through points (2, 5) and (3, 7). Does this trend line illustrate a correlation

zalisa [80]

Given that the scatter plot contains a trend line that passes through (2,5) and (3,7),
the slope of this line is given by:
slope,m=(7-5)/(3-2)=2/1=2
this shows a positive slope, but other than this we cannot draw any further details concerning the points such as the correlations, hence the answer is:
<span>D. There is not enough information.</span>

Fine the slope of the line perpendicular to the line graphed below

goldenfox [79]

Answer:

$-\frac{1}{2}$

Step-by-step explanation:

The slope of this line is 2 because the rise from one point is 2, and the run is 1. The change in y-value is divided by the change in the x-value which is 2/1, hence, the slope of the line being 2.

The slope of the line perpendicular to the one shown below will be $-\frac{1}{2}$ because the slope that will result in a perpendicular line is the negative reciprocal of the original slope.
