The slope-intercept form:

m - slope
b - y-intercept
We have the equation in standard form.
<em>subtract 2x from both sides</em>
<em>divide both sides by (-3)</em>

Answer:
I'm a alien, sorry.
Step-by-step explanation:
Angles 2, 6, and 7 because angle 1 = 115 so that makes angle 4 = 115 so angle 2 must also be 65 so angle 4 and 2 = 180 and the same goes for angles 5,6,7,8
1 kilometers =1000 meters
0.86km=0.86*1000=860m
John swam 860 meters each day.
1 week = 7 days
3weeks=3*7=21
21*860=18060 m
Therefore he swam 18060 meters in those three weeks.
