in the xy-plane above, point c has coordinates (6,9). which of the follwoing is an equation of the line that contains points 0 and c?



Answer :

MattD
C(6,9)
D(0,0)
y=ax+b
From D(0,0):
0=0*a+b
b=0
From C(6,9):
9=6*a+0
6a=9|:6
[tex]a=\frac{9}{6}=\frac{3}{2}[/tex]
[tex]y=\frac{3}{2}x+0[/tex]

"Above ..." means look at the picture over the question, and "Following ..." means
stay tuned, there's a list of choices coming right after the question.  The picture
and the list are both part of the question. There's no way to understand the
question clearly without the picture, and no way to answer the question
"Which... ?" without some choices.

You also have not explained where the point ' 0 ' is.  Is it at the origin, where
'x'  and  'y'  are both zero ?  Or is it some somewhere else ?
