Document Summary

Linear function passing through the origin: where m is the slope. Slope: slope intercept form where m is the slope and b is the y-intercept. Use this when you know the slope and the y-intercept of the line. You can only use when you know the y-intercept: point-slope form. This can be used whenever you know the slope and any other point of the line. This is more general and more useful than slope intercept: example: find the intercepts of linear function y-intercept = (0,5) To find the y-intercept, let x=0 and solve for y x-intercept = ( To find the x-intercept, let y=0 and solve for x: example: a city had a population of 375 thousand on july 1, 2000 and was growing at a rate of 9. 25 thousand each year. Find the formula constant rate = 9. 25 elapsed time = 375.
