SOL

A.6b - The student will graph linear equations and linear inequalities in two variables, including writing the equation of a line when given the graph of the line, two points on the line, or the slope and a point on the line.

Slope-Intercept Form

Observe what happens as you move the two sliders.

Graphing Lines using Slope-Intercept Form

Use the points to graph the line given in slope-intercept form. (Hint: Use one point for your y-intercept and the other for slope)

CORRECT! NICE WORK! Will appear once the equation is graphed correctly.

  1. Slope & Intercept: What is the significance of the slope of a line? Y-Intercept?
  2. Slope-Intercept Form: Think of the equations for the lines as being in the form y = mx + b. What effect do the m and the b have upon the graph of the line? How could you graph the line y = -2x + 4 without plotting points?
