Answer:

<h2>y=<u> -2</u>x+<u>7</u></h2>

<u>Here</u><u>,</u>

Two points given: (3,1) and (7,-7)

slope(m) =  \frac{y2 - y1}{x2 - x1}  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  =  \frac{ - 7 - 1}{7 - 3}  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  =  \frac{ - 8}{4}  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  =  - 2 \\

Equation of line is y= Mx+b

y= -2x +b

It passes through (3,1)

1 =  - 2(3) + b \\ 1 =  - 6 + b \\  - b =  - 6 - 1 \\  - b =  - 7 \\ b = 7

Equation of line:

<h3>y= -2x+7</h3>

Hope this helps..

Good luck on your assignment..

A new computer loses 1/2 of its value every year. Which graph could represent the relationship between the year and the computer
Igoryamba

<u>Let's first consider:</u><em> the fact that a new computer loses 1/2 of its value</em>

<em> </em>  ⇒ <u>third choice</u> and <u>fourth choice</u> are <u>eliminated</u>

    ⇒ because of the graph project the computer's value as growing over  

         years

<u>Now let's try to set up an equation</u>:

After 1st year ⇒ Computer's value = total_.value*\frac{1}{2}

After 2nd year ⇒ Computer's value = total_.value*\frac{1}{2}*\frac{1}{2}=total_.value*(\frac{1}{2}  )^2

After 3rd year ⇒ Computer's value =total_.value*\frac{1}{2}*\frac{1}{2}* \frac{1}{2}=total_.value*(\frac{1}{2})^3

     

 ..... (<em>Hopefully you see a pattern)</em>

<em />

After x year ⇒ Computer's value = total_.value*(\frac{1}{2})^x

<u>Therefore, the equation is</u>: total_.value*(\frac{1}{2})^x

  ⇒that means the graph has to <u>exponentially decreasing</u> as it has

     an exponent (<em>meaning the function is exponential</em>) and a base less

     than 1 (<em>meaning that the function is decreasing)</em>

<u>Answer: Choice (1)</u>

<u></u>

Hope that helps!

Help me with this answer I know there is no solution I just wanna know why
mylen [45]

Answer:

The solution x = 0 means that the value 0 satisfies the equation, so there is a solution. “No solution” means that there is no value, not even 0, which would satisfy the equation. ... This is because there is truly no solution—there are no values for x that will make the equation true
