The line through the two given points has slope
.. (1 -(-3))/(4 -(-4)) = 4/8 = 1/2

The perpendicular line will have a slope that is the negative reciprocal of that,
.. -1/(1/2) = -2

So, the point-slope equation of your line is
.. y -3 = -2(x +4)

.Answer:

The rate of change for y=x+6 is less than the slope of the line represented by the table.

Step-by-step explanation:

First let's look at our equation:

$y=x-6$

This equation is written in slope-intercept form:

$y=mx+b$

Where m is the slope of the line and b represents the y-intercept.

Therefore in our equation:

$y=x-6$

Our slope is 1 (invisible 1 in front of x since 1 times x is x) and it also has a y-intercept of -6.

Next let's look at our table and choose any two points. In this case I choose (0,-5) and (5,10). It doesn't matter which two you decide to choose. Now, let's calculate the slope of this line by using the following equation.

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} =\frac{10+5}{5-0}= \frac{15}{5} =3$

and so the line that the table represents is more than to y=x-6. Furthermore, the equation for the table is y=3x-5, this is because (0,-5) is the y-intercept for this line.

Which statement explains the relationship of sides BA and B'A' after rectangle BADC has been rotated 90° clockwise about the ori

Leni [432]

Answer:

Numbering the options, we have;

1) Side B'A' has a slope of −1 and is perpendicular to side BA.

2) Side B'A' has a slope of 1 and is parallel to side BA.

3) Side B'A' has a slope of 1 and is perpendicular to side BA.

4) Side B'A' has a slope of −1 and is parallel to side BA.

The correct option is;

1) Side B'A' has a slope of -1 and is perpendicular to side BA

Step-by-step explanation:

The given coordinates are;

A(3, 5) B(1, 3), C(5, -1) and D(7, 1)

The slope of BA is found as follows;

$Slope \, of BA= \dfrac{y_{2}-y_{1}}{x_{2}-x_{1}} =\dfrac{3-5}{1-3}= \dfrac{-2}{-2} = 1$

Rotation of a line through 90 degrees gives

(x, y) will be (y, -x)

Therefore, the coordinates of A' = (5, -3)

The coordinates of B' = (3, -1)

Then the slope is given as follows;

$Slope \, of \, B'A' =\dfrac{-1 -(-3)}{3-5}= \dfrac{2}{-2} = -1$

Therefore side B'A' has a slope of -1 and is perpendicular to side BA.
