Chapter 3 Review Function: Each value of x corresponds to exactly one value of y. Vertical Line Test: If no vertical line can be drawn so that it intersects a graph more than once, the graph is the graph of a function. Domain: the set of all x values of a graph Range: the set of all y values of a graph Standard Form Ax + By = C Slope-Intercept Form y = mx + b slope is m, y-intercept is (0,b) Point-Slope Form y – y 1 = m(x-x 1 ) slope is m, (x 1 ,y 1 ) is a point on the line Horizontal Line y = b slope is 0, y-intercept is (0,b) Vertical Line

Unformatted text preview: x = c slope is undefined, x-intercept is (c,0) Two lines are parallel if they have the same slope and different y-intercepts Two lines are perpendicular if the product of their slopes is -1 (the slope of one is the negative reciprocal of the other) Vertical lines are perpendicular to horizontal lines To find x-intercept : let y=0 and solve for x To find y-intercept : let x=0 and solve for y Or put equation into slope-intercept form Slope m = rise run = 2 1 2 1 y y x x--...
