On to the Challenge!
A tangent line “touches” a graph at exactly one spot. Here’s an example of a tangent line:
Here’s an example of a line that is not tangent to the curve (because it intersects the curve at two points):
Here’s an example of a line that is not tangent to the curve (because it doesn’t intersect the curve at all):
And now the challenge: Can you graph a line that is tangent to the circle at one of the points shown on the graph? See how many points you can “touch” with tangent lines. (Click the graph to go to a live version at Desmos.com.)
