Review of Slope-Intercept Form: y = mx + b is the slope-intercept form of a linear equation. This equation will give you the graph of a line when at least 2 points are identified as being on the line. The two important parts of this equation: m is the slope of the line and b is the y- intercept of the line expressed as an ordered pair (0.b). Remember every solution to the equation is a point on the line and every point on the line is a solution to the linear equation. Practice Problems: Evaluate the following equations for integer values of x from -3 to 3. Express final answer as an ordered pair. Determine if the line is increasing or decreasing. 1).y = 3x 2).y = -3x 3).y = 3x - 1 5).y = -x 7).y = -x-2 4). y = -3x + 2 6).y = -x + 1 8).y = -x-3 Review of Slope-Intercept Form: y = mx + b is the slope-intercept form of a linear equation.
