which of the following represent the equation of a line with the slope of 1/4 that passes through the point (-8,2)

Answers

Answer 1

Answer:

Answer:

The equation of a line with the slope of 1/4 that passes through the point (-8,2) is $y=(x)/(4)+4$

Solution:

Given, slope of a line is $(1)/(4)$ and a point is (-8, 2)

We have to find the line equation with above given values.

Now, we know that, point slope form of a line is

$y-y_(1)=m\left(x-x_(1)\right)$

Where, m is slope of line and $\left(x_(1), y_(1)\right) \text { is point on that line. }$

Here in our problem, $\mathrm{m}=(1)/(4) \text { and }\left(\mathrm{x}_(1), \mathrm{y}_(1)\right)=(-8,2)$

So, substitute above values in general form.

$\begin{array}{l}{y-2=(1)/(4)(x-(-8))} \n\n {y-2=(1)/(4)(x+8)}\end{array}$

4(y – 2) = (x + 8)

4y – 8 = x + 8

x – 4y + 8 + 8 = 0

x – 4y + 16 = 0.

4y = x +16

$y=(x)/(4)+4$

Hence the equation of a line with the slope of 1/4 that passes through the point (-8,2) is $y=(x)/(4)+4$

Answer 2

Answer:

Answer:

y = 1/4x + 4 or y - 2 = 1/4(x + 8)

answer is A

First try to break up your values as perfect squares we know that 2x 25 = 50 So putting them under the radical to square root is
✔️25 x ✔️2 is the same as ✔️50, but square of 25 is 5 so it comes outside the radical and you are left with 5✔️2. Sorry I dont have or know where myvsquare root sign is on my iphone keypad. The answer is A.?

What is a decagon?

A decagon is a 2D shape, or polygon that has 10 straight sides, 10 vertices (points), and 10 interior angles.

Given that, A 2-inch-wide frame is to be built around the regular decagonal window

External angles add up to 360

so each external angle = 360/10 = 36 degrees

internal angle = 180 - 36 = 144 degrees

Hence, angles at the corners are 144 degrees
