m is the slope and b is the y-intercept. So if your equation is y = 1/4x – 3, then your m is 1/4 and your b is -3. So, 1/4 is the slope and -3 is the y-intercept.

Hope that helps!

The slope m of this line – its steepness, or slant – can be calculated like this:

m = change in y-value

change in x-value

The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept.

The y-intercept of this line is the value of y at the point where the line crosses the y axis

or if this isn’t helping or confusing go to math.com

in the form y = mx+b, m is always the slope, and b is always the y intercept..

In your question, the slope (m) is 1/4, and the y intercept (b) is -3

See, slope is what comes right before x, and right after x is the y intercept. This should always be true in the level of math you’re doing.. (comp 7/8? algebra I?)

y-intercept: -3
