Answer:
M= -2
B=1
Step-by-step explanation:
<u><em>Y-intercept</em></u><em> is the point where the line crosses through the y line, so you can clearly see that that point is (0,1) we only write the y value because for a y intercept the x value will always be zero</em>
<em><u>Slope</u></em> <em>is the rise over run, meaning how much the y value changes over how much the x value changes, so for the two points we use our formula:</em>

<em>So now input how much it changes by adding the numbers from each coordinate:</em>

<u>Simplify:</u>
<u />
<u />
<em>But we write it as:</em>
-4/2
<em>This is because this looks more like division</em>
<u>Divide:</u>
-4/2=-2
So, your slope is <em><u>-2</u></em> and the y- intercept is <em><u>1</u></em>
I hope this helps u pls give a brainliest and a thx ;)
One way you could solve this is to just multiply the top and bottom out so that you get 9/81, reducing it by 9/9 to get 1/9 or option C.
Another way would be to do

since dividing numbers with exponents would be subtracting the bottom exponent from the top exponent, provided that the base number (in this case 3) is the same for both. For this method, you would get

, which is equal to 1/9 or .1 repeating, the same answer that you'd get with the first method.
Y=68+4x
100=68+4x
-68=-68
32=4x
Divide both sides by 4
x=it will take 8 min. for the water to reach 100 degrees
y=total degrees
x=# of minutes

Answer:
C
Step-by-step explanation:
I typed it into a graphing calculator. You could also choose a point (I choose (4,0) ) then plug it into each equation In the answers until you get back the numbers of the point you choose to represent x and y. For example
