A coordinate plane with a line passing through (0, negative 4) and (2, 0). What is the equation of the graphed line written in s

Hoochie [10]

Answer:

d) The equation of the line passing through the points

$y = \frac{-x}{2} - 4$

Step-by-step explanation:

Step(i):-

Given points are ( 0, -4) and (2 ,0)

slope of the line

$m = \frac{y_{2}- y_{1} }{x_{2}- x_{1} } = \frac{2-0}{0-4} = \frac{-2}{4}= \frac{-1}{2}$

Step(ii):-

The equation of the line passing through the point ( 0,-4) and having slope

$m = \frac{-1}{2}$

$y - y_{1} = m ( x - x_{1} )$

$y - (-4) = \frac{-1}{2} ( x - 0 )$

2 ( y +4) = -x

2 y + 8 = -x

2 y = - x - 8

$y = \frac{-x}{2} - \frac{8}{2}$

$y = \frac{-x}{2} - 4$

Final answer:-

The equation of the line passing through the points

$y = \frac{-x}{2} - 4$

I really need the answer to this. Date: 04/25/17

dimaraw [331]

The answer is

I know this because I did (4 x 11 x 30) + (7 x 20 x 11)

This is also equal to 1320 + 1540 = 2860. Hope this helped!

Need help with Select Expansion or Contraction to correctly describe the type of dilation for each given scale factor.

ad-work [718]

To know if a dilation is an expansion ( bigger) r a contraction ( smaller) ignore the negative sign.

If the number is larger than 1, it is an expansion, if the number is smaller than 1 it is a contraction.

-4 is an expansion

2.5 is an expansion

2/3 is a contraction

-3/4 is a contraction

V = 105/8

Step-by-step explanation:

Volume of a box is length time width times height

V = l*w*h

= 7/2 * 5/2 * 3/2

= 105/8
