Find the slope of a line parallel to the line 3x+7y=-2.

Step 1. Put the equation in slope-intercept form given as y=mx+b where m is the slope and b is the y-intercept when x=0 or point (0,b).

Step 2. Subtract 3x from both sides of the equation

3x%2B7y-3x=-2-3x

7y=-3x-2

Step 3. Divide 7 to both sides of the equation

7y%2F7=-3x%2F7-2%2F7

y=-3x%2F7-2%2F7

Step 4. Comparing y=-3x%2F7-2%2F7 withy=mx%2Bb we see that the slope m=-3%2F7 and the y-intercept b=-2%2F7.

Step 5. ANSWER: The slope is m=-3%2F7

I hope the above steps were helpful.
