A linear function is a function that can be graphically represented in the Cartesian plane as a straight line, defined by the equation $$f(x) = mx + b$$ where $$m$$ is the slope and $$b$$ is the y-intercept.

To solve an equation means to find the value(s) of the variable(s) that make the equation true.

The slope-intercept form of a linear equation is $$y = mx + b$$ , where $$m$$ is the slope and $$b$$ is the y-intercept.

The y-intercept is -5, which is the value of $$f(x)$$ when $$x = 0$$ .

To evaluate a function at a given point, substitute the value of the variable into the function's equation and simplify.
