Answer:

8.0623

Explanation:

Distance between two points = √ ( − 2 − − 9 )^ 2 + ( − 2 − − 6)^ 2

= √ 7 ^2+ 4 ^2

= √ 49 + 16

=√ 65 = 8.0623

Distance between points (-9, -6) and (-2, -2) is 8.0623

{-2x+y=12 => y=12+2x

{3x+2y=38

3x+2(12+2x)=38

3x+24+4x=38 /-24

7x=14 /:7

x=2

y=12+2*2=12+4=16

y=16

<em>Solution: (2; 16)</em>

Please help with the following question

sasho [114]

We have:
The generic equation of the line is: y-yo = m (x-xo)
The slope is:
m = (y2-y1) / (x2-x1)
m = (- 2-0) / (3-0)
m = -2 / 3
We choose an ordered pair
(xo, yo) = (0, 0)
Substituting values:
y-0 = (- 2/3) (x-0)
Rewriting:
y = (- 2/3) x
Answer:
The equation of the line is:
y = (- 2/3) x
