First off, I would like to say that you aren't d**b! Always remember that asking for help is never d**b!
To change a fraction to a decimal, put the decimal over its place value. For example, if you had the decimal 0.7, you would put 7 over 10 to create the fraction 
.
Lastly, always remember to simplify your answer!
Hope this helps! Have a great day! (:
15.8% would round to 16%
If the number after the decimal point is 5 or greater you round the 5 up to a 6. If it had been less than a 5 it would have rounded down to 15%.
(-1,-10)(0,-6)
slope = (-6 - (-10) / (0 - (-1) = 4/1 = 4
y = mx + b
slope(m) = 4
(0,-6)...x = 0 and y = -6
sub and find b, the y int
-6 = 4(0) + b
-6 = b
ur equation is : y = 4x - 6

Answer: x = 1, y = -2
Step-by-step explanation:
-9x+2y=-13
x= 13/9 + 2/9y
2x-9y=20
2(13/9+2/9y)-9y=20
<em>Substitute y with -2.</em>
<em />
x= 13/9+2/9(-2)
<em>After solving you'll see that 1 is a possible solution for x.</em>
<em />
Check your answer
-9x+2y=-13
-9x1+2(-2) = -13
2x-9y=20
2x1-9(-2) = 20
-13 = -13
20 = 20
Therefore, x=1 and y=-2
