Question

If AB is parallel to CD and the slope of AB IS -3 what is the slope of CD?

Answer 1

Answer:  The slope of CD = -3

Step-by-step explanation:

We know that the property of parallel lines says that "if two lines are parallel , then their slopes are equal."

The given statement : AB is parallel to CD and the slope of AB is -3

Therefore, by the property of parallel lines, we have

The slope of CD = slope of AB

Therefore, The slope of CD = -3

Answer 2

since parallel lines have the same slope, If the slope of AB is -3 then the slope of CD will also be -3
