Question:
When solving a problem on slopes,and in the formula y=mx+b what do the M and B stand for? Why M and B?

Hi Selena

In the standard equation for a line, y = mx + b, m designates the slope of the line, and b the y-intercept, that is b is the second coordinate of the point where the line crosses the y-axis. Why m and b is an interesting question. We have been asked that question a number of times and the short answer is that we don't know. Look here for a more detailed answer.
