Verifying the Slope and y-Intercept of from its Graph
By examining the graph of the linear equation , one can visually verify its slope and y-intercept. The graph crosses the y-axis at the point , confirming the y-intercept is . Starting from this intercept and tracing the line to another integer coordinate, such as , reveals a rise of unit upwards and a run of units to the right. Using the slope formula , the slope is calculated as . These visually extracted values match the coefficient of (which is ) and the constant term (which is ) in the equation, illustrating how an equation in slope-intercept form directly describes the features of its graph.
