Answer:

We can express the equation for any linear equation with slope -2 and point (x0,y0) as:

y=-2x+(y_0+2x_0)\\\\y-y_0=-2(x-x_0)

Step-by-step explanation:

Incomplete question:

There is no point to complete the equation.

As we have no point to complete the linear equation, we will solve for any given point (x0,y0) and a slope of m=-2.

The linear equation can be written generically as:

y(x)=mx+b\\\\y(x)=-2x+b

If a point, like (x0,y0) belongs to the linear equation, it satisfies its equation. Then:

y_0=-2x_0+b

Then, we can calculate b as:

y_0=-2x_0+b\\\\b=y_0+2x_0

We can express the equation for any linear equation with slope -2 and point (x0,y0) as:

y=-2x+(y_0+2x_0)\\\\y-y_0=-2(x-x_0)

Y = 230x + 100<br> Is this proportional or non proportional?
Svet_ta [14]
<h3>Answer:  Non proportional</h3>

Proportional equations are of the form y = kx, for some fixed constant k. The k value is the constant of proportionality.

The +100 at the end is why we don't have a proportional equation.

Visually all proportional equations go through the origin, meaning the lines have y intercept of 0. For y = 230x+100, the y intercept is 100.

-2 1/3 plus 5 1/5<br> Can you please help me answer this problem
Ket [755]

Hey there!☺

Answer:\boxed{2\frac{13}{15}}

Explanation:

-2\frac{1}{3}+5\frac{1}{5}

Add the fraction together.

-2\frac{1}{3}+5\frac{1}{5}=\frac{43}{15}

Let's simplify 43/15.

\frac{43}{15}=2\frac{13}{15}

2\frac{13}{15}

Hope this helps!
