Why is slope m and y-intercept B?
In the equation y = mx + b for a straight line, the number m is called the slope of the line. Let x = 0, then y = m • 0 + b, so y = b. The number b is the coordinate on the y-axis where the graph crosses the y-axis.
Why do they call the y-intercept B?
We teach it backwards. The fancy letter for the slope is m. So we change the basic equation to include the slope notation… Turns out that the b here is also exactly where the line smacks into the y-axis – AKA the y-intercept. But there’s no fancy letter for that, so we just leave it as b.
Is the y-intercept M or B?
In the equation of a straight line (when the equation is written as “y = mx + b”), the slope is the number “m” that is multiplied on the x, and “b” is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named the “slope-intercept form”.
Why do they use M for slope?
It is not known why the letter m was chosen for slope; the choice may have been arbitrary. John Conway has suggested m could stand for “modulus of slope.” One high school algebra textbook says the reason for m is unknown, but remarks that it is interesting that the French word for “to climb” is monter.
What does the M and B stand for in slope?
m is the slope of the line (change in y/change in x) and b is the y intercept of the line (where the line crosses the y axis).
What is slope and y intercept?
The slope and y-intercept values indicate characteristics of the relationship between the two variables x and y. The slope indicates the rate of change in y per unit change in x. The y-intercept indicates the y-value when the x-value is 0.
What does the B stand for in slope intercept form?
Definition of slope-intercept form : the equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept.

What is the relationship between the slope and the y-intercept to the systems of linear equations?
Slope and y-Intercept Values The slope indicates the rate of change in y per unit change in x. The y-intercept indicates the y-value when the x-value is 0.
