<PRE><B>Question 174096</B>
you must write this in slope intercept form y=mx+b where m is the slope 
:
we must isolate the y term
:
7x+9y=27.....first subtract 7x from both sides of the equation
:
9y=-7x+27....next divide all terms by 9
:
y={{{highlight(-7/9)}}}x+3).......now it is easy to see
:
what the slope is(the number in from of the x) so m or slope is -7/9</PRE>
