Slope equals 2 and the line goes through the point (-1, 3)

astra-53 [7]

Answer:

Well the slope seems rather easy to calculate because you already typed it and it is 2.

First we must solve this equation:

b = y - m*x and we input values into the equation:

b = (3) - (2 * -1)

b = 5

Then, we enter the value of "b" and the slope into this equation:

y = mx +b

y = 2x + 5

Appended below is the code for Selection Sort. You really do not have to understand the details of the code. If this algorithm t

kramer

Answer:

12 seconds.

Step-by-step explanation:

Let t represent time taken by code to sort an array of 24 elements.

We have been given that an algorithm takes 4 seconds to sort an array of 8 elements. We are asked to find the time it will take for same code to sort an array of 24 elements.

We will use proportions to solve our given problem.

$\frac{\text{Time}}{\text{Array of elements}}=\frac{4}{8}$

$\frac{t}{24}=\frac{4}{8}$

$\frac{t}{24}\cdot 24=\frac{4}{8}\cdot 24$

$t=\frac{4}{1}\cdot 3$

$t=12$

Therefore, it will take 12 seconds for the same code to sort an array of 24 elements.
