What is the slope of the line 6x + 8y = 12?

The answer is - 3/4 because you would subtract 6x from both sides then divide 8 from both sides.

You need to turn this equation ... into something that looks like y = mx + b * notice the 'y' is by itself on the left side ... so how would you get 'y' by itself on the left side in your equation?

alternative : if given a straight line ax + by = c, then the slope always m = - a/b

Actually, just to make it easier on this exact question ... use what RadEn has shown. You have an equation ax + bx = c to find the slope ... you do slope = - a - - - b So your equation, what is 'a' and what is 'b'? 6x + 8y = 12
