1. Rectangular m-by-n matrices Rule for transposes: (AB)T = BT AT The matrix AT A is always square, symmetric, and positive semi-definite. If in addition A has linearly independent columns, then AT A is positive definite. Take C a diagonal matrix with positive elements. Then AT CA is always square, symmetric, and positive semi-definite.

A linear equation is an equation for a straight line. These are all linear equations: y = 2x + 1 : 5x = 6 + 3y : y/2 = 3 − x: Let us look more closely at one example: Example: y = 2x + 1 is a linear equation: The graph of y = 2x+1 is a straight line . When x increases, y increases twice as fast, so we need 2x;

Both equations have a slope of -2. Since the slopes are the same, these lines are parallel. To locate an ordered pair (a, b) on the coordinate plane: 1. Locate x = a on the x-axis, then draw a perpendicular line through the point. 2. Locate y = b on the y-axis, then draw a perpendicular line through the point. 3.
