Thank you so much ladies. </p> https://boards.hellobee.com/topic/calling-all-math-lovers#post-2626491 Fri, 23 Sep 2016 11:42:00 +0000 SweetiePie 2626491@https://boards.hellobee.com/ <p>@MrsLonghorn: Woohoo I was right but you typed it out way more eloquently than I could have. I would have had a hard time explaining how I got there. </p> https://boards.hellobee.com/topic/calling-all-math-lovers#post-2626488 Fri, 23 Sep 2016 11:38:18 +0000 MrsLonghorn 2626488@https://boards.hellobee.com/ <p>I was a math major in college and LOVE stuff like this! I left a message on your wall. </p> <p>So, you want to figure out the slop of the line passing through (−2,0) and (−4,−5). The formula for slope is "y2-y1"/"x2-x1". So, -5-0/-4--2 = -5/-2 = 5/2.</p> <p>To be parallel, the other line must have the same slope. So using (7,k) and (8,−8) gives us: (-8-k)/(8-7) = (-8-k)/1 = 5/2<br /> So, by cross multiplying the fractions, we get 2*(-8-k) = 5<br /> -16-2k = 5<br /> -2k = 21<br /> k = -10.5</p> <p>You can double check your work: if the slope for both lines is 5/2, then increasing x by 2 means you increase y by 5. Therefore, increasing x by 1 means increasing y by 2.5.<br /> Going from (7, -10.5) to (8, -8) you did exactly that -- x increases by 1, and y increases by 2.5!</p> <p>It is really hard to type this out , but I'd be happy to email with you or even chat. I tutored math all through college and really enjoy this. </p> https://boards.hellobee.com/topic/calling-all-math-lovers#post-2626484 Fri, 23 Sep 2016 11:31:35 +0000 SweetiePie 2626484@https://boards.hellobee.com/ <p>Can the value for k be a half value? I'm coming up with -10.5 and not sure if that's ok?<br /> I also haven't taken a math class in 13+ years but I used to be pretty good once upon a time. I calculated the slope of the line with two points you do know. Plotted the next point on the line with unknown k (since they are parallel lines the slope would be the same). And then figured out what k would be from there.<br /> ETA I don't know if this is right, I'm rusty. </p> https://boards.hellobee.com/topic/calling-all-math-lovers#post-2626467 Fri, 23 Sep 2016 11:06:52 +0000 Mrs. Lion 2626467@https://boards.hellobee.com/ <p>I can't find a video for exactly this type of problem, but you would use a similar strategy to this one :) </p> <p><a href="https://www.youtube.com/watch?v=WkiPVButdeg" rel="nofollow">https://www.youtube.com/watch?v=WkiPVButdeg</a> </p> https://boards.hellobee.com/topic/calling-all-math-lovers#post-2626465 Fri, 23 Sep 2016 11:02:03 +0000 bubblegum 2626465@https://boards.hellobee.com/ <p>I'm just a few credits shy of graduating and of cause I left all my Math courses for last. I HATE MATH. It's only week 1 and I already feel like I'm drowning. Any who there's a problem I'm really stuck on. Any have any ideas on what I should do to solve?</p> <p>Find the value of k so that the line containing the points (7,k)(and (8,−8) is parallel to the line containing the points (−2,0) and (−4,−5).</p> <p>I already e-mailed my teacher but just in case anyone has some idea. Thanks in advance! </p>
