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

Step 1. We can find the slope by recognizing that parallel lines have the same slope.

Step 2. Need to put above line in slope intercept form given as y=mx+b where m is the slope and b is the y-intercept b when x=0 or at point (0,b).

Step 3. Solving for y in 3x+7y=-2 yields the following steps.

Subtract 3x from both sides of the equation

Divide by 7 to both sides of the equation

Step 4. Comparing with we have and

Step 5. ANSWER: The slope of the parallel line is -3/7.

I hope the above steps and explanation were helpful.
