Choose the point-slope form of the equation below that represents the line that passes through the point (6, -3) and has a slope of one half. y - 6 = one half(x + 3) y = one halfx - 6 y + 3 = one half(x - 6) x - 2y = 12
@amistre64
for starters, we need to know what point slope form looks like in general. any ideas?
um not really
what line form equations do you know of? maybe we can narrow it down some
give ,me a sec let me see ,my notes
slope intercept form
i see a slope intercept form up there, so we know thats not the answer. do you see which one we can get rid of?
yea D
D is in standard form, B is slope intercept also, the names of the form tend to define what we use to create them. slope intercept is made using the slope and the y intercept. point slope is made by using any given point, and the slope, to construct it with. we want an option that uses the point values and the slope value
so A is the answer right?
yes :)
thanks!
notice that a line has the same slope between any 2 points. given a point (x,y) and a point (a,b) we can use the slope formula to construct a line \[\frac{y-b}{x-a}=m\] mathing out the bottom converts it to point slope form \[{y-b}=m({x-a})\] and my computer is sooo slow at the moment
youre welcome :)
help me out wit another one? i tagged u already
i havent got the notif of the tag yet. but ill bee there soon. others have tagged me as well.
