Best ResponseYou've already chosen the best response.1earlier we found line BC to be \[\Large y = \frac{2}{3}x+\frac{20}{3}\]

Best ResponseYou've already chosen the best response.0Yes, would it be the same for AD?

Best ResponseYou've already chosen the best response.1but the same steps will be used find the slope of AD (since it's parallel to BC, the two slopes are equal). Then use it to find the equation of line AD

Best ResponseYou've already chosen the best response.1you also need the equation for line CD

Best ResponseYou've already chosen the best response.0For AD equation, would it start like: y14=m(x2)? m = slope

jim_thompson5910

Best ResponseYou've already chosen the best response.1yes and m = 2/3 because AD and BC have the same slope (they are parallel lines)

Best ResponseYou've already chosen the best response.0So, then I can plug in 6 to get the x value for D?

Best ResponseYou've already chosen the best response.1yes you can plug in y = 6. I didn't see D(?,6)

Best ResponseYou've already chosen the best response.0Yeah, sorry, with my packet, I have image of it showing the C point being on 0. So, helped me determine the distance for the AD y and what to subtract.

Best ResponseYou've already chosen the best response.02/3 * 2 would be 12/3?

Best ResponseYou've already chosen the best response.0614=2/3(x2) 8=2/3x + 4/3 It ends up being: 6 = 2/3x + 28/3 right?

Best ResponseYou've already chosen the best response.1now solve for x

Best ResponseYou've already chosen the best response.1oh I see what went wrong

Best ResponseYou've already chosen the best response.1When you went from 8=2/3x + 4/3 to 6 = 2/3x + 28/3 you made an error the 6 in ` 6 = 2/3x + 28/3` should be 0 so you should have 0 = 2/3x + 28/3

Best ResponseYou've already chosen the best response.1it's 0 because you added 8 to both sides the 8 and +8 combine to 0 on the left side

Best ResponseYou've already chosen the best response.0To be honest, I read my graph wrong aswell, so I was confused. I lack in graphing, but all is well. You really helped and taught me a few things, I hope to remember. (:
