D. y=-3/10x+1/2

Step-by-step explanation:

Using rise/run you can count the units the line moves from one point to another, from the left point to the right point the line travels down 3 and over 10 so you get -3 as your rise (it is negative because the line is traveling downwards) and 10 as your run, so your slop is -3/10. By looking at the graph you can see that your y-intercept is 1/2. SO when plugged into y=mx+b with m as -3/10 and b as 1/2 you get the equation y=-3/10x+1/2, or letter D.

I need to find two consecutive positive integers such that the square of the first is decreased by 17 equals to 4 times the seco
aleksandrvk [35]
So, is two integers, and they must be consecutive, meaning, the next one will have to be either 1 before the first or one after... anyhow.

let's say the first integer is "a".

then a consecutive integer to that one will be just 1 hop away, or say "a + 1", so there, those are the two integers.

now, we know that 

\bf \stackrel{\textit{square of the first is decreased by 17}}{a^2-17}~~=~~\stackrel{\textit{4 times the second}}{4(a+1)}
\\\\\\
a^2-17=4a+4\implies a^2-4a-21=0\implies (a-7)(a+3)=0
\\\\\\
a=
\begin{cases}
\boxed{7}\\
-3
\end{cases}

so, is a positive integer, so it can't be -3.

what's the second integer?  well is a + 1.
