Best ResponseYou've already chosen the best response.0Sorry, I'm a little dimwitted, but isn't "0=10" a bit, illogical? I'm being a bit confrontational because it doesn't look like my example in the txtbook, even though I don't understand it.

Best ResponseYou've already chosen the best response.1r=(3,2,7)+t(3,6,2) r=(3+3t,2+6t,7+2t) sub in 3x2y+4z=5 3(3+3t)2(2+6t)+4(7+2t)=5 9+9t412t+28+8t=5 15+5t=5 5t=10 t=2

Best ResponseYou've already chosen the best response.1if you had the equation y=2x + 3 does the point (3,9) lie on the line yes it does .. check sub it in 9=(2)(3)+3 9=9 true now when you make 3 planes x,y,z your just check does the point lie on the plane they use word points and vector interchangeably
