what is the equation of the line that passes through the point (-2,-2) and is parallel to the line 3x-y=2

VashaNatasha [74]

Answer:

y = 3x + 4

Step-by-step explanation:

Turn the equation from standard form to slope intercept form. So, solve for y.

3x - y = 2

~Subtract 3x to both sides

-y = 2 - 3x

~Divide -1 to everything

y = -2 + 3x

~Reorder

y = 3x - 2

The slope of a parallel line is the same as the original.

Find the new y-intercept.

y = 3x - 2

-2 = 3(-2) + b

-2 = -6 + b

4 = b

y = 3x + 4

Best of Luck!

Use the order pairs to find the linear equation in slope intercept form (0,10) & (3,2)

Virty [35]

$y = \frac{-8}{3}x + 10$ is the equation in slope intercept form

Solution:

Given points are (0, 10) and (3, 2)

We have to find the slope intercept form

Let us first find the slope of line

The slope of line is given as:

$m = \frac{y_2-y_1}{x_2-x_1}$

Here,

$(x_1, y_1) = (0, 10)\\\\(x_2, y_2) =(3,2)$

Substituting the values we get,

$m = \frac{2-10}{3-0}\\\\m = \frac{-8}{3}$

The equation of line in slope intercept form is given as:

y = mx + c ------- eqn 1

Where, "m" is the slope of line and "c" is the y intercept

Substitute $m = \frac{-8}{3}$ and (x , y) = (0, 10) in eqn 1

$10 = \frac{-8}{3} \times 0 + c\\\\c = 10$

$Substitute\ m = \frac{-8}{3}\ and\ c = 10\ in\ eqn\ 1$

$y= \frac{-8}{3}x + 10$

Thus the equation of line in slope intercept form is found

For a fixed amount of a gas at a constant temperature, the volume of the gas is inversely proportional to its pressure. At a pre

Veronika [31]

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form $y*x=k$ or $y=k/x$

Let

x-------> the pressure in PSI

y------> the volume of the gas in cubic inches

In this problem we have the point $(30,600)$

$x=30\ psi\\y=600\ in^{3}$

Find the constant k

$y*x=k$

substitute the values of x and y

$600*30=k$

$k=18,000\ lb*in$

the equation is

$y=18,000/x$

therefore

the answer is

$y=18,000/x$
