We just figured out that a line with a slope of 3 and a y-intercept of 2 has the equation y = 3x + 2. What if we want to know the equation for this line? ... Most people call the slope m and the y-intercept b. If we do that, we can rewrite our equation in a shorter form:

Date: 01/20/97 at 11:59:07 From: Doctor Lisa Subject: Re: x and y intercepts and graph Hi Sarah! Let's take a look at your question step by step. The first thing you told me is that you need to get the equation into y = mx + b form.

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? ... 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...

Education in mathematics and science. ... Also, notice that when the y-intercept, b, is positive, the line crosses the y-axes above y = 0. When b is negative, the line crosses the y-axis somewhere below y = 0. In fact, b is the value on the y-axis where the line passes through this axis.

A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and (the first power of) a single variable. Linear equations can have one or more vari...

Question: I am looking for origin of the use of "m" for slope in the "y=mx+b" form of, a linear equation. While you are at it perhapsexplains why the "b" was used for the y-coordinate of the y-intercept. I am of the opinion that "m" was used by Descartes for montee, i.e. "going up".

a standard way of writing the equation of a line, y = mx + b, to indicate its slope, m, and the coordinate of one point on that line, the y-intercept, (0, b). EX. Write 4x - y = 10 in slope-intercept form.

Using two points on the same line, find the slope and the y-intercept. Then write the equation of the line in slope intercerpt form. Also, you may be asked to do only one step in this process (find m or find b).
