Which equation describes a line parallel to y= 4x+ 5 through point (-2, 1)?

Tema [17]

Hi there!

For a line to be PARALLEL, it must contain the same slope.

The given line has a slope of 4, so we can use the point-slope formula to solve:

$\large\boxed{y - y_1 = m(x - x_1)}$

y1 = y-coordinate of given point

x1 = x-coordinate of given point

m = slope

Plug in the values:

$y - 1 = 4(x - (-2))\\\\y - 1 = 4(x + 2)$

Simplify:

$y - 1 = 4x + 8\\\\\boxed{y = 4x + 9}$

Find the coordinates of midpoint D. (a + bc) (-a-b,c) (2a-2b, -c) (-2a-2b, c)

schepotkina [342]

Answer:

(-a-b,c)

Step-by-step explanation:

midpoint D : ((-2b-2a)/2 ;(2c+0) /2 )

(-2b-2a)/2 = 2(-b -a)/2 = -b-a

(2c+0) /2 =2c/2 = c

What is the median of the data set?

olga2289 [7]

<h3>Answer: 8.5 (choice B)</h3>

=========================================================

Explanation:

The diagram shows us we have this data set

{5, 8, 8, 8, 8, 9, 9, 9, 10, 10}

Cross off the outer most items (the 5 and the second 10) to get this smaller set

{8, 8, 8, 8, 9, 9, 9, 10}

Repeat the last step of crossing off the outer most items to get

{8, 8, 8, 9, 9, 9}

Keep this process going until we have this set of steps

{8, 8, 9, 9}

{8, 9}

We have two items left, which are tied for the middle, so we compute the midpoint

(8+9)/2 = 17/2 = 8.5 is the median

This is the middle most value
