 Question 390505: The library charges 50 cents a week for a late book. What is the equation for the total fee? What are the variables? What are the x and y intercepts? I am also trying to find the slope of the line.Answer by ewatrrr(11176)   (Show Source): You can put this solution on YOUR website! ``` Hi, Letting y represent the amount of the fine, and x the number weeks late Write as we Read y = .5x (amount in dollars for the fine) Using the standard slope-intercept form for an equation of a line y = mx + b where m is the slope and b the y-intercept. slope m = .5 = 1/2 y-intercept (when x=0) is Pt(0,0) x-intercept (when y = 0) is Pt (0,0) Note: slope of the line: as y increases/decreases by 1, x increases/decreases by 2 ```
