Unformatted text preview: f L is the number m =
x1 − x0
2 The slope-intercept form of L is y = mx + b where b is the
y -intercept of L.
3 The point-slope form of L is y − y0 = m(x − x0 ). 4 The standard form of L is ax + by = c for some constants a,
b , and c , with a and b not both zero. Outline Three Forms of a Linear Equation Graphing Linear Equations The Point-Slope Form of a Line Applications The Slope-Intercept Form and Graphing The slope-intercept form of a line is convenient for graphing
We read oﬀ the y -intercept and plot it.
