The y-intercept is where the graph crosses the y-axis
Set x = 0
Substitute x = 0 into the equation
Solve for y
Write the intercept as the point (0, y)
For a line in slope-intercept form y = mx + b, the y-intercept is b
For an equation in standard form Ax + By = C, set x = 0 and solve for y
For a table, find the y-value when x = 0
For a graph, identify the point where it crosses the y-axis
