Answer:

y = 4x - 1

Step-by-step explanation:

(1, 3) ; (2 ,7 )

$Slope =\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{7-3}{2-1}\\\\=\frac{4}{1}\\\\= 4\\\\\\y - y_{1} = m(x -x_{1})\\\\y - 3 = 4(x - 1)\\\\y - 3 =4x - 4\\ y = 4x - 4 + 3\\y = 4x - 1$

Let t[1..n] be a sorted array of distinct integers, some of which may be negative. give an algorithm that can find an index i su

lisabon 2012 [21]

Assuming we need to find i such that
1 ≤ i ≤ n and t[i]=i.

If we need to find only the first occurrence, we can do:

for i:1 to n {
if t[i]=i then return(i)
}

If exhaustive search is required, then put the results (values of i) in an array or a linked list, return the number of values found, and the array (or linked list).
