Question

Line EF passes through the points (0, 1) and (3,3). Line GH passes through the points (3, -3) and (6, -1). These lines are

A) skew. B) parallel. C) concurrent. D) horizontal.

Answer 1

parallel

Explanation:

The solution is parallel. We can use the slope formula to calculate the slope of the two lines. Both lines have a slope of

2/3

. Since the lines have the same slope, they are parallel. Since the y-intercepts are different, the lines are not concurrent. This can be seen best if you sketch the two lines.

m = y2 - y1

x2 - x1

Answer 2

The correct answer is b
