Graphing Linear Functions! How to graph quickly without using tables of values!
A linear function is of the form f(x) = mx + b where 'm' and 'b' are real numbers. Isn't it looking like the slope-intercept form of a line which is expressed as y = mx + b? Yes, this is because a linear function represents a line, i.e., its graph is a line. Here,
'm' is the slope of the line
'b' is the y-intercept of the line
'x' is the independent variable
'y' (or f(x)) is the dependent variable
