Answer:

m= -2/3 b=(0,1)

Step-by-step explanation:

Make your first point at (0,1). then go down 2 over 3. do that until you run out of room. then go back to your first point and go up 2 over 3.

(13 points) solve this determinant...

pashok25 [27]

Answer:

z - x.

Step-by-step explanation:

| 0 0 x-z |

| 0 1 y+z | = 0 |1 y+z| + 0 | 0 y+z| + x-z | 0 1 |

| 1 z z^2 | ||1 z^2| | 1 z^2 | | 1 z |

= 0 + 0 + (x - z)(0*z - 1*1)

= -(x - z)

= z - x

Which rectangle if reflected over the x-axis and then translated 8 units right will result in rectangle E?

Komok [63]

Answer:

Rectangle D is reflected over the x-axis and then translated 8 units right will result in rectangle E

Step-by-step explanation:

The coordinates of rectangle D are:

(-1, 1)

(-1, 4)

(-3, 1) and

(-3, 4)

The rule of reflection across x-axis is given by:

$(x, y) \rightarrow (x , -y)$

$(-1, 1) \rightarrow (-1 , -1)$

$(-1, 4) \rightarrow (-1 , -4)$

$(-3, 1) \rightarrow (-3 , -1)$

$(-3, 4) \rightarrow (-3 , -4)$

Next, translate this 8 unit right which is given by:

$(x, y) \rightarrow (x+8 , y)$

$(-1, -1) \rightarrow (-1+8 , -1) =(7, -1)$

$(-1, -4) \rightarrow (-1+8 , -4) =(7, -4)$

$(-3, -1) \rightarrow (-3+8 , -1) =(5, -1)$

$(-3, -4) \rightarrow (-3+8 , -4) =(5, -4)$

⇒(7, -1) , (5, -1) , (5, -4) and (7, -4) represents the coordinate of rectangle E.

Therefore, Rectangle D if reflected over the x-axis and then translated 8 units right will result in rectangle E

What is the equation of the line with the given slope and y-intercept? Choose the correct answer in slope-intercept form and sta

kari74 [83]

Answer:

see explanation

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y-intercept )

here m = $\frac{1}{3}$ and b = 13, hence

y = $\frac{1}{3}$ x + 13 ← in slope- intercept form

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and AB, C are integers )

multiply all terms in the slope-intercept form by 3

3y = x + 39 ( subtract 3y from both sides )

0 = x - 3y + 39 ( subtract 39 from both sides )

x - 3y = - 39 ← in standard form
