Explanation
The correct answer is . For a line that passes through the points and in the xy-plane, the slope of the line can be calculated using the slope formula, . It's given that a line passes through the points and in the xy-plane. Substituting for and for in the slope formula, , yields , or . Therefore, the slope of the line is . Note that 18/11 and 1.636 are examples of ways to enter a correct answer.
