Line k is defined by y = 17 7 x + 4 . Line j is parallel to line k

Question

Line k is defined by y = 17 7 x + 4 . Line j is parallel to line k in the xy -plane. What is the slope of line j ?

Accepted Answer

Choice B is correct. It's given that line k is defined by y = 17 x 7 + 4 . For an equation of a line written in the form y = m x + b , m is the slope of the line and b is the y -coordinate of the y -intercept of the line. It follows that the slope of line k is 17 7 . It's also given that line j is parallel to line k in the xy -plane. Since parallel lines have equal slopes, line j also has a slope of 17 7 . Choice A is incorrect and may result from conceptual or calculation errors. Choice C is incorrect. This is the y -coordinate of the y -intercept of line k , not the slope of line j . Choice D is incorrect and may result from conceptual or calculation errors.
