What is the equation of the function that is graphed as line b?

alina1380 [7]

-- Look at the places where the line crosses the 'x' axis and the 'y' axis.
   Between those two points, it goes forward 2 units, but only rises 1 unit.
   So the slope of the line is 1/2 .

-- Look again at the point where the line crosses the y-axis.
   At that point, y=1 .
   That's the "y-intercept".

Now you have the slope and y-intercept of the line.

The equation of ANY straight line is

   y = (slope)x + (y-intercept) .

You know what they both are, so you can easily write

   y = 1/2 x + 1 .

Is that one of the choices ?
Yes it is.
Good enough for me.
That must be the correct one.

With no "blah blah blah" required.

What is 143/13 as a mixed numeral?

yuradex [85]

Answer and Step-by-step explanation:

$Hello!$

$Here~I~will~show~you~how~to~~convert~an~improper~fraction~into~$ $a~mixed~number!$

$To~find~the~answer~we~simply~divide~143~by~13.$

<u><em>→ We get our answer as:</em></u>

<u><em /></u> $\frac{143}{12}=11$ <u><em /></u>

<u><em /></u>

<u><em /></u> $Now,~that~we've~got~11~as~our~answer,~Let's~see~what~a~mixed~number$ $is~so~that~we~can~convert~it.$

<em><u>→ What does mixed fraction mean? :</u></em>

<em><u /></em> $It~simply~means,~a~mixed~number~has~an~integer~that~is~a~whole$ $integer. So,~to~make~it~into~a~mixed~number~we~need~an~integer~and~$ $a~fraction~so~we~can~write~it~as:$

$=11\frac{0}{13}$

<u><em>→ And that's your answer!</em></u>
