<PRE><B>Question 176932</B>
The solution posted by Checkley is INCORRECT for #9 and 10!!  It is beyond me how anyone who has posted SO MANY solutions on algebra.com could make such a GREVIOUS error!!


To find the slope you must first solve for y.

9. 2y + 2x = 18
2y = -2x +18


Divide each side by 2:
y = -x + 9
The slope is -1


10. 6x + 5y = 10
5y=-6x+10


Divide both sides by 5:
{{{y=(-6/5)x+2}}}
The slope is {{{-6/5}}}
