Determining Solutions to Equations Using Graphs

This lesson teaches how to determine if a coordinate pair is a solution to an equation by using its graph. It covers graphing equations like X^2 + Y^2 = 25 and X + Y = 4, showing how to plot points and identify the shape of the graph. The lesson also explains how to verify solutions using algebra, demonstrating with examples like (3,2) and (-4,-3).

Describe how the graph of an equation represents all of its solutions.

What steps can be taken to verify if the point (-4, -3) is a solution to the equation X^2 + y^2 = 25?
