x − 3 y = − 9 − 3 y = − x − 9 / : ( − 3 ) y = 3 1 x + 3
To convert the equation x − 3 y = − 9 into function form, we rewrite it as y = 3 1 x + 3 . The graph can be created by plotting the y-intercept (0, 3) and using the slope of 3 1 . Points can be calculated easily for more accuracy in the graph.
