Is there anyone here will do paper 4 before Monday PM

 

[3os]

um there was a question in my paper saying:​

find the k in these equations of lines:​

5x+4y=10​

14=2y-kx​

​

What i did is i simply rearranged them, then i put (-5) as k because it is a parallel line therefore gradients are equal right????​

​

I think the equation was 5x=4y+10
