Line a is parallel to line b. Which statement about lines a and b is true?
2 answers:
Answer : The correct option is, line a and b have same slope.
Step-by-step explanation :
As we know that:
The slope of two parallel lines have same slope.
The slope of two perpendicular lines have (-1) slope.
When slope of line is zero then the line is parallel to x-axis.
When slope of line is undefined then the line is parallel to y-axis.
As we are given that the two lines are parallel to each other. So, the slope of two parallel lines will be equal.
Hence, the correct option is, line a and b have same slope.
