Slope-intercept form is one way of expressing a linear function (a fancy name for a straight line) as an equation.
The slope-intercept form is modeled in the following way:
y=mx+b
where m represents the slope of the line and brepresents the y-intercept.
Slope represents rate of change (how much y values change in relation to x) and on a graph determines how "sloped" a line is. Values of m close to 0 mean the line is more horizontal, or less sloped. As m approaches negative infinity or positive infinity, the line becomes more vertical, or more sloped.
The y-intercept is simply the coordinate where the line crosses the y-axis on a Cartesian Plane. The point is (0, b).
The slope-intercept method is popular because of its convenience. Using it, a graph of the line can be constructed very easily by hand without having to rearrange the equation. That said, in practical applications where computer software or graphing calculators are used, the form of a linear equation is less important. Slope-intercept form is often used by teachers and school textbooks.

What is the form of an equation for a horizontal line?
For a horizontal line, it is y= a value
When a line is perpendicular to a line segment what angle do they form at their intersection?
a right angle
What is a linear line?
The term "linear line" is redundant; lines are necessarily linear, since linear means in the form of a line.
Can irrational numbers represent on a number line?
No ,irrational no can not be represented on no line because it is not of the form p/
How do you graph if there is no slope?
If there is no slope in a graph, it means that the line is horizontal. A horizontal line has a slope of zero. To graph a horizontal line, you simply draw a straight line that is parallel to the x-axis. The equation of a horizontal line is typically in the form y = k, where k is a constant value.
