At every point along a function, the function has a slope that we can calculate. Doing that gives us the slope of the function at the point, but also the slope of the tangent line to the function at that point. I create online courses to help you rock your math class. Read more. The normal line is the line which is perpendicular to the tangent line at the point where the tangent line intersects the function. Which means that, if the slope of the tangent line is???

We previously wrote the equation for a linear function from a graph. Now we can extend what we know about graphing linear functions to analyze graphs a little more closely. Begin by taking a look at the graph below. We can see right away that the graph crosses the y -axis at the point 0, 4 , so this is the y -intercept. Then we can calculate the slope by finding the rise and run. To get from this point to the y- intercept, we must move up 4 units rise and to the right 2 units run. So the slope must be:.
Prism does not automatically write equations on the graph. You can see the numerical results of linear or nonlinear regression by going to the appropriate page in the Results folder. Prism 6 or later: The equation is written out at the bottom of the results page. Copy that and paste onto the graph.
