Answer 2

you do online school too?

Answer 3

No its a class I have online though!

Answer 4

I have no idea what these double arrow things are but I am going to assume I can just use the equation of a line

so if you know two coordinates
\[(x_{1},y_{1}),(x_{2}, y_{2})\]
so in your case
(8,0),(3,7)

then you can use the equation to work out the slope

\[m=\frac{ y_{2}-y_{1} }{ x_{2}-x_{1} }\]

then use the equation of a line
\[y-y_{1}=m(x-x_{1})\]

Answer 5

thanks!

Answer 6

then you would multiply out the bracket, and get it into the form y=mx+b

then! to work out CD
you know the point D(5,5)
so you would let x=5, y=5
and you know m from before and you would work out the new b
so you would just do

5=m(5)+b
(replace m with whatever you worked out before, since they are parallel, they have the same slope)

work out b then you would simply write

y=mx+b

(again, replace m with what you had before, and replace b with what you just worked out)
this would be CD

Answer 7

I hope that made sense

work it out step by step, and show your working out here I will correct you if needed

Answer 8

thanks so much!!!
