Determine the slope of a parallel to the folling line 9x + 7y = 10

Recall that the slope formula is y=mx+b (m is the slope)

You need to first get y by itself, to do that you subtract 9x on both sides of the equation

9x+7y=10 subtract 9x to the left side where it will cancel it because you're adding a positive to a negative number that are the same, then you subtract 9x to the right side of the equation

when you do that you should get: 7y = - 9x+10

Now you divide 7 on both sides

you then should get: y = - 9/7x-10/7
