5.5 a Writing Linear Equations in Standard Form
Standard Form Ax + By = C E1 3x+2y = 8 A= 3 B= 2 C= 8
Standard Form Rules Ax + By = C A cannot be negative A and B both not zero A,B, and C are integers (whole numbers) There can be no GCF
Write each equation in Standard Form. Identify A, B, & C. E2 5x = 10y + 15 E3 3y = 2x
Write each equation in Standard Form. Identify A, B, & C. E5 3y – 6 = x E4
The x-intercept is the point where the graph of the line crosses the x-axis. Plug zero in for y, then solve for x The y-intercept is the point where the graph of the line crosses the y-axis. Plug zero in for x, then solve for y
