Draw the graph of an inequality whose slope is 3, y-intercept is -1, boundary line is a solid line, and the solution set is the lower half-plane.

A candidate has budgeted $9,900 to spend on radio and television advertising. A radio ad costs ​$495 per​ 30-second spot and a television ad costs ​$900 per​ 30-second spot. How many radio and television spots can the candidate purchase without exceeding the​ budget? Express your answer as a linear inequality with appropriate nonnegative restrictions and draw its graph. Let x be the number of radio spots and let y be the number of television spots. Choose the correct answer below and graph the inequality.     A. 495x+900y≤9,900​, x≥​0,y≥0   B. 495x+900y<9,900​, x≥​0,y≥0   C. 495x+900y≥9,900​, x≥​0,y≥0   D. 495x+900y>9,900​, x≥​0,y≥0

My question is attached as a jpeg.

A candidate has budgeted $7,200 to spend on radio and television advertising. A radio ad costs ​$360 per​ 30-second spot and a television ad costs ​$800 per​ 30-second spot. How many radio and television spots can the candidate purchase without exceeding the​ budget? Express your answer as a linear inequality with appropriate nonnegative restrictions and draw its graph.
