In this case the slope (which we often just call "m") is 8. The slope is the value in front of the x, including the minus sign if there is one. The model for the slopeintercept form is
where m is the slope and b is the yintercept. Notice that in my example earlier, the yintercept is 7. This means that the line intercepts the y axis at y=7, in other words, it passes through the point (0, 7). To rearrange the equation, you just use the usual algebra rules to "solve for y". Here is another example that is close to your question: what is the slope of 15  3y = 6x:
Now this is in the y = mx + b form, so I can see that the slope is 2. Now try your question. Cheers,
