To write an equation for a graph, you first need to determine the type of equation that best fits the shape of the graph.
For example, if the graph is a straight line, you can use the slope-intercept form of a linear equation: y = mx + b, where m is the slope of the line and b is the y-intercept.
If the graph is a parabola, you can use the standard form of a quadratic equation: y = ax^2 + bx + c, where a, b, and c are constants.
If the graph is a circle, you can use the equation for a circle: (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center of the circle and r is the radius.
Once you have determined the type of equation that corresponds to the graph, you can use the given information to plug in the appropriate values for the constants in the equation.
