Answer:

4x + y = 4

Step-by-step explanation:

Equation of Line in point slope form is given as:

y - y_1= m(x-x_1)

Plug x_1= 2\: and\: y_1= - 4 in the above equation we find:

y - ( - 4) =  - 4(x - 2) \\  \\ y + 4 =  - 4x + 8 \\  \\ 4x + y + 4 - 8 = 0 \\  \\ 4x + y - 4 = 0 \\ \\ 4x + y = 4 \\this \: is \: the \: required \: equation.

4x + y = 4

First we can use the info to make a slope intercept form equation

y = -4x +4 (since slope is -4 and when x= 2, y = -4)

then change to slope intercept form (ax + by = c)

4x + y = 4

An amount of $180 is shared among three people in the ratio x: y: z.
sammy [17]

Answer:

$110 and $30

Step-by-step explanation:

To solve this, we need to know the total share which is,

4 + 11 + 3 = 18

Then, you need to know the fraction of the share over the total, such that

x = \frac{4}{18}

y =  \frac{11}{18}

z =  \frac{3}{18}

So if to find how much that'll be of the $180 for the largest and smallest share,

Largest:

\frac{11}{18}  \times 180 = 110

Smallest:

\frac{3}{18}  \times 180 = 30

Hi,

Work:

Equation;

y = \frac{2x}{1 + {x}^{2} }

Root = (0, 0)
Domain: x = R
Vertical Intercept = (0, 0)

Hope this helps.
