We can do so by manipulating the equation as shown. Use a graph and two points to find slope without the equation handy. And the best way to view it slope is equal to change in y over change in x.
Some call the y-coordinates the rise and the x-coordinates the run.
We can do so by manipulating the equation as shown. The equation of a horizontal line is y b where b is the y-intercept. Graph a line with coordinates. And sometimes you might see it written like this.
