Slope-Intercept Form Example
For example: Find the slope and y-intercept for this graph
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.
