The equation of a line is y=mx+b, when m is the slope of the line and b is the y-intercept.

y=mx+b is the equation for a linear relationship. y= the dependant variable m= the slope of the line x= the independent variable b= the y-intercept

In the equation Y=mx+b, which is what I believe you mean, 'b' is the y intercept of the graph. In other words, if the equation is plotted in standard Cartesian coordinates, the straight line crosses the y-axis at the height b above the x axis.

In the straight line equation: y = mx+b 'm' is the slope and 'b' is the y intercept

If the equation of a line is in the form ax + by + c = 0 then the slope of the line will be -a/b.

General form for a line equation is: y=mx+b.

A line with a zero slope is a horizontal line with an equation y = b, where b is any real number on the y-axis. It means that the line y = b intersects y-axis at b. You also can write the equation of a horizontal line in the slope-intercept form, such as y = 0*x + b.

There is no equation there but the slope of the line is the number that multiplies x in the straight line equation y = mx + b whereas m is the slope and b is the y intercept
