Slides in Comparing Slopes
Remember, that a line with a positive slope is increasing (goes up from left to right).
1) 'm' always represents the slope.
2) Slope-intercept form is y = mx + b, where 'm' is the slope and 'b' is the y-intercept.
Remember, slope can be calculated using the slope formula. It doesn't matter if you have a table, graph, or a set of points. Calculate the slopes of the three linear functions represented on this slide.
Remember, the y-intercept is the location at which the graph crosses the y-axis. The y-intercept ALWAYS has the x-value "0".
