Answer:

Step-by-step explanation:

use the point slope equation.

y-y1 = m(x-x1)

the point is (x1, y1) = (2, -1)

the slope is m = -3

y+1 = -3( x-2)

y = -3x +6-1

y = -3x +5

Nitella [24]

Answer:

Step-by-step explanation:

The equation of a straight line can be represented in the slope-intercept form, y = mx + c

Where c = intercept

Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis

change in the value of y = y2 - y1

Change in value of x = x2 -x1

y2 = final value of y

y 1 = initial value of y

x2 = final value of x

x1 = initial value of x

The line passes through (2,-1) and (4,5),

y2 = 11

y1 = 5

x2 = 10

x1 = 4

Slope,m = (11 - 5)/(10 - 4) = 6/6 = 1

To determine the intercept, we would substitute x = 4, y = 5 and

m = 1 into

y = mx + c. It becomes

5 = 1 × 4 + c = c + 4

c = 5 - 4 = 1

The equation becomes

y = x + 1

The standard form is represented as

Ax + By + C = 0

y - x - 1 = 0

Multiplying through by - 1, it becomes

x - y + 1 = 0

You are given the following information: Stockholders' equity = $323 million; price/earnings ratio = 14; shares outstanding = 8,
vagabundo [1.1K]

Answer:

$282.59 per share

Step-by-step explanation:

Given that,

Stockholders' equity = $323 million

price/earnings ratio = 14

shares outstanding = 8,800,000

Market/book ratio =7.7

Book Value per share:

= Stockholders' equity ÷ shares outstanding

= $323,000,000 ÷ 8,800,000

= $36.70

Market price per share:

= Book Value per share × Market/book ratio

= $36.70 × 7.7

= $282.59 per share
