Graphing Linear Equations in Standard Form In your own words, write the meaning of each vocabulary term. standard form Core Concepts Using Intercepts to Graph Equations The x-intercept of a graph is the x-coorclinate of a eoint where the graph crosses the x-axis. It occurs when = 0. (0, b) They-intercept of a graph is they-coordinate of a point where the graph crosses they-axis. It occurs when x = 0. y-intercept = ·b) -intercept =.a) 0 (a, To graph the linear equation Ax + By = C, find the intercepts and draw the line that passes through the two intercepts. • To find the x-intercept, let y = 0 and solve for x. • To find they-intercept, let x = 0 and solve for y. Horizontal and Vertical Lines The graph of y = b is a horizontal line. The line passes through the point {0, b). The graph of x == a is a vertical line. The line passes through the point (a, 0).
