Mathematics Questions …

Filed under: Technical — Porcupyn @ 2:39 pm

Without looking at the answer/comments, solve these two questions, and say how much time you took to come up with the answer!

Write an equation in slope-intercept form for a line that is parallel to the given line and passes through the given point. x=4; (-7,3)

Write an equation in slope-intercept form for a line that is perpendicular to the given line and passes through the given point. y=3; (4,-2)

  1. OK, pardon my ignorance…but x=3 is essentially (4,0) and y= 3 is (0,3)…is that what you mean? Coz, it totally beats me otherwise….I eman I need to have two co-ordinates OR a co-ordinate and the slope. I don’t think you would just give out the slope.

    If my assumption is right, I got the answer “pretty fast”. If the assumption is wrong, I never got the answer.

  3. D.S.:

    That just shows that you bunked too many geometry classes in your day. See if you can get some help from your better half!🙂

    Rads:

    Well, I respond to e-mails faster than to tags.😉

    So, where is your solution? Or that of K1 or K2?

  4. ah, the man speaketh! Tag? What tag? My tag or yours?🙂

    Answer? You kidding me right? My expertise with numbers is confined to spreadsheets and making them look like pieces of art. Slopes and such send me off the curve..

    Check mail.

  5. My answers:

    1) x = -7
    2) x = 4

    Any disagreements?

    rads:

    Tags = Self-inflicted ones, like an audio for that tongue-twisting rhyme …
