For example: Find the slope and y-intercept for this graph [br]         [img width=168,height=119]https://lh6.googleusercontent.com/NSOcwSn6_R4crws2AVmbfqZEeVPptRJQcfLc6x0q0ZF490cSj2Jm_jRPiik3h21FebCFIG5zY1fe2Rl0w8XKoFRKtEm2ZztryMZqHBZnY96Abjfqch-OJ42LsqNz8YRoR7_51LD9[/img][br]Finding the y-intercept is the easiest of these, go to the y-axis and find where the line passes through and that is the y-intercept. For this line the y-intercept is 10 and now in order to find the slope you have to use slope formula or use rise / run. I'll be using rise / run since it works faster so, rise (10) and run (20) being 10 / 20 which reduced is 1 / 2. Placed into Slope-Intercept Form is y=1/2x+10.[br]
