Unformatted text preview: To find a y-intercept, let x = 0 and solve for y. Example: Graph 2x + 3y = 6 by plotting intercepts. When a linear function is written in the form y = mx + b or f(x) = mx + b, the y-intercept is (0, b)! Example: What are the x- and y-intercepts of f(x) = 2x 4? Graphing Vertical and Horizontal Lines The graph of x = c is a vertical line with x-intercept (c, 0) The graph of y = c is a horizontal line with y-intercept (0, c) Examples: Graph x = -2 Graph y = 4...
