In this part of the video, the speaker discusses translating a picture into equations for circles using the distance formula. They remind viewers about the formula: distance = sqrt((x1-x2)^2 + (y1-y2)^2) which originates from Pythagoras’ theorem. The speaker emphasizes the importance of learning the formula before it’s provided as reference in more advanced years. The video demonstrates how to apply the distance formula for points on a circle, where they calculate the distances for x and y coordinates using specific values.

In this part of the video, the speaker discusses how selecting a radius of three affects the diagram. They explain that the radius being three means it is the same everywhere, leading to adjustments in the diagram. The speaker then simplifies the equation without square roots and demonstrates how to determine the radius and center of the circle using the given equation. They provide an example with a radius of 11 squared to illustrate the concept.

In this segment of the video, the speaker discusses finding the center of a graph. They mention that the x-coordinate will be 7 and emphasize that the y-coordinate is essentially y – 0 squared, though it is not explicitly written as such. The speaker explains that knowing the equation allows you to determine important details about the graph.
