Line c passes through points (2, 1) and (9, 10). Line d is parallel to line c. What is the slope of line d?

Question

I want to know what is the slope for this question "Line c passes through points (2, 1) and (9, 10). Line d is parallel to line c. What is the slope of line d?"

Answer 1

Line c has two known points, so from those (x,y) ordered pairs, you can compute the slope, m (it's change in y over change in x).

 

Since line d is parallel to c, its slope will be the same as what you just computed.
