Graph linear and quadratic functions and identify intercepts, maxima, and minima.
Use slope-intercept form to list graphing features of a line
Problem
Extract graphing features from \(y=2x+3\).
Big Picture
What this problem is really about
Slope-intercept form is a compact set of graphing instructions: one parameter locates the vertical-axis crossing and the other describes a repeatable rise-over-run move. We’ll read those roles separately, generate a second point from the intercept, and substitute that point back into the equation as a consistency check.
