What angle does the graph of the linear function y = kx form with the positive direction of the x-axis, if k is greater than 0, k is less than 0.
With a positive coefficient at x, the graph of the function y = kx passes through the first and third quarters and, therefore, forms an acute angle with the positive direction of the x-axis.
With a negative coefficient at x, the graph of the function y = kx passes through the second and fourth quarters and, therefore, forms an obtuse angle with the positive direction of the x-axis.
