Slope-Intercept Form of the Linear Equation
- Carlos B. Vizcaino
If a line has a slope m and the y-intercept is b, then the line is described by the equation y=mx + b
1. Graph the equations y = 2x + 3 then y = -2x + 3. How does the sign of m affect the graph of the equation? 2. How does changing the value of m affect the graph of an equation in the form y = mx + b? 3. Graph the equations y = 2x + 3 y = 2x - 3 y = 2x + 2. Where does the graph of each equation cross the y-axis? 4. How does the changing of the value of b affect the graph of an equation in the form y = mx + b?
