Explanation

The correct answer is 5 13 . The graph of a line in the xy-plane can be represented by the equation y = m x + b , where m is the slope of the line and b is the y-coordinate of the y-intercept. The given equation can be written as y=513x-23. Therefore, the slope of the graph of this equation in the xy-plane is 5 13 . Note that 5/13, .3846, 0.385, and 0.384 are examples of ways to enter a correct answer.
