What is the slope of the line 8x + 6y = 30

The form for the y-intercept equation is y=mx+b where m=the slope. If we can get it into that format, it will give us the slope. So we need to solve for y.

8x+6y=30

To simply things, we are going to divide the whole equation by 2. So the equation is now:
4x+3y=15

We need to move the 4x to the right side so we subtract 8x from both sides
4x-4x+3y=15-4x
3y=15-4x

Now we need to get y alone so we divide by 3
3y/3=

We can separate that fraction and we have:


Now that we have it in the right format we can see that if you look at the formula y=mx+b then m=  

Hope that helps.

B. 2 1/2 feet. multiply 2.5 inches by 12 to get thirty inches then divide by 12 to get 2.5 feet
