<PRE><B>Question 82194</B>
the general form of the slope-intercept equation is y=mx+b, where m is the slope and b is the y-intercept


you have to use algebra to get y by itself on one side of the equation, then the coefficient of the x term is the slope


-6x-9y=12 ... adding 6x to both sides gives -9y=6x+12 ... dividing the equation by -9 gives y=-(2/3)x-(4/3)


so the slope is -2/3 ... and the y-intercept is -4/3</PRE>
