Answer explanation

The correct answer is 44 3 . A linear equation can be written in the form y=mx+b, where m is the slope of the graph of the equation in the xy-plane and 0,b is the y-intercept. Distributing the 1 3 in the equation y=1329x+10+5x yields y=293x+103+5x. Combining like terms on the right-hand side of this equation yields y=443x+103. This equation is in the form y=mx+b, where m = 44 3 and b = 10 3 . Therefore, the slope of the graph of the given equation in the xy-plane is 44 3 . Note that 44/3, 14.66, and 14.67 are examples of ways to enter a correct answer.
