Answer:

Step-by-step explanation:

Y=mx+b

so find your slope

y2-y1/x2-x1 so 13-7/4-2

you get 6/2 or simplified 3

so now you have the equation y=3x+b

next you want to plug in a point to your equation so

7=3(2)+b

now solve using PEMDAS

7=6+b

then you want to isolate your variable

7 = 6 + b

-6 -6

1=b and thats your slope intercept

hope this helped :)

The function of x is $\bold{\frac{-1x}{2}}$ .

<u>SOLUTION:</u>

Given that, we have to write a linear function f with function of (-4) =2 and function of 6=(−3).

Now, let the linear function be $\text{function of x}=a x+b$

Then, function of -4 = $a(-4)+b \rightarrow 2=-4 a+b \rightarrow b=2+4a \rightarrow (1)$

And, function of 6 = $a(6)+b \rightarrow-3=6 a+b \rightarrow b=-3-6a \rightarrow (2)$

On equating (1) and (2) to find the value of a,

$2+4a=-3-6a$

On grouping the common terms,

$4a+6a=-3-2 \rightarrow 10a=-5 \rightarrow a=\frac{-5}{10}$

$\Rightarrow a=\frac{-1}{2} \rightarrow (3)$

On substituting the value of (3) in (1) we get,

$b=2+4a \rightarrow b=2+4\times\frac{-1}{2} \rightarrow b=2+\frac{-4}{2} \rightarrow b=2+(-2)$

$\Rightarrow b=0$

So, the function of x = $\frac{-1x}{2}+0$

How would you find values of m for question 'b'?

Trava [24]

This is known as quadratic algebra.

To find it, you can use the quadratic formula but that might take a while.

We can factor it out and get

-3(mx² + mx - 1)

We can then set mx² + mx = 1

It would have no solutions

Edit: Above is wrong! I made the mistake of factoring 3 when it cant be factored.

Here is the solution

mx²-3mx=-3

Divide both by -3

mx²+mx=1

And I really messed this up. Its been a long time since quad. Sorry, but I cant seem to get the answer. Try and look up the quadratic formula and see if you can use that

Ron gets $5 on the first day at work, the square of that amount on the second day, and three times the amount of the second day

kvv77 [185]

1st day= $5
2nd day = 5^2 = $25
3rd day = 25×3= $75
5 + 25 + 75 = $105
