Explanation
The correct answer is . It's given that line is defined by . It's also given that line is parallel to line in the xy-plane. A line in the xy-plane represented by an equation in slope-intercept form has a slope of and a y-intercept of . Therefore, the slope of line is . Since parallel lines have equal slopes, the slope of line is . Note that 1/4 and .25 are examples of ways to enter a correct answer.
