A linear equation in slope-intercept form is written as {eq}y=mx+b{/eq} where {eq}m{/eq} is the slope of the line and {eq}b{/eq} is the {eq}y{/eq} intercept, the point at which the graph of the function crosses the {eq}y{/eq}-axis. ...
A function whose graph is a straight line is called alinear function. A function is linear if its equation can be expressed in the form {eq}f(x)=mx+b {/eq} where {eq}m {/eq} is the slope and {eq}b {/eq} is the {eq}y{/eq}-intercept of the line. ...

This linear formy = ax + bis called the slope-intercept form of the equation of a straight line. Because, as we shall prove presently, a is the slope of the line (Topic 8), and b -- the constant term -- is the y-intercept.This first degree form...
The graph of the equation y2 = x3 2x2 + x looks like: Since many vertical lines cut this graph at more than one point, this is not the graph of a function. 1.2. Examples: Example 1.2. Linear Functions: A linear function is a function of the form f(x) = mx + b (where m ...
