A) y= -2x-3/2

B) y= -3/2x + 2

C) y= 2/3x-7/3

I recommend you do the following:

Rearrange the equation into the form $\displaystyle y = mx+c $. $\displaystyle m$ will be the gradient, hence find which equations from list have the same gradient. Then input your point into the equation and solve for c, and find the c that matches from the list. - May 30th 2010, 01:55 PMdnntau
