4.6 Slope-Intercept Form Exploration
Slope intercept Form.
Type in the given equations in slope intercept form( y = mx + b ).
What do you notice?
We know slope is the rise over run. We know the y-intercept is where the line crosses the y-axis.
Do you see the slope in the equation? Do you see the y intercept?
Which is m? Which is b?
What happens when you have 2 equations that have the same slope but different y intercepts?
What happens when you have 2 equations and their slopes are opposite signs and reciprocals of each other? Examples y = 4x + 6 and y =- .25x + 6
