Question
Can you help me figure how to find the slope number to this equation?

2x-3y+6=0

Answer
All lines can be put in the form y = mx + b, where m is the slope and b is the y intercept.
That is, when x = 0, y = b.

For this line, there is a 2x and 6 ln the left that should be on the right.
So, add -2x-6 to both sides and get -3y = -2x - 6.

Next, we have a -3 in front of y, and it should be 1, so divide all terms by -3.
This gives y = (2/3)x + 2.

When it is in this from, m is always the slope.
Here, m = 2/3.
