You can put this solution on YOUR website! The y-intercept is the point where the line crosses the y-axis.
The slope is the change in divided by the change in .
So choose two points and use the x and y coordinates to find the slope.
You can put this solution on YOUR website! Suppose you have a linear equation:
------------------
The y-intercept is where
so, making ,
The y-intercept is at ( 0. -11 )
----------------------------
The slope is
here's the plot:
