The points (6, 9) and (0, 6) fall on a particular line. What is its equation in slope-intercept form?

SashulF [63]

Answer:

$y = \frac{1}{2}x + 6$

Step-by-step explanation:

$Let \ (x _1 y _ 1 ) = ( 6 , 9 ) \ and \ (x _ 2 , y _ 2 ) \ = ( 0 , 6 )\\\\$

Step 1 : Find slope, m

$slope, m = \frac{y _ 2 - y _ 1}{x_ 2 - x_ 1 } = \frac{6 - 9}{0 - 6 } = \frac{-3}{-6} = \frac{1}{2}$

Step 2 : Find the equation

$(y - y _ 1 ) = m ( x - x_ 1) \\\\( y - 9 ) = \frac{1}{2} (x - 6 ) \\\\y = \frac{1}{2}x - 3 + 9 \\\\y = \frac{1}{2}x + 6$

Answer:

The direct distance between the birds is 12.64 miles.

Step-by-step explanation:

We have, one bird flew 12 miles west and another bird flew 4 miles north. It is required to find the direct distance between the birds. It means we need to find the resultant of two displacement. It can be given by :

$d=\sqrt{12^2+4^2} \\\\d=12.64\ \text{miles}$

So, the direct distance between the birds is 12.64 miles.
