Question

Is the line through points P(0, 5) and Q(–1, 8) parallel to the line through points R(3, 3) and S(5, –1)? Explain.

a.
No, the lines have unequal slopes.
b.
Yes, the lines are both vertical.
c.
Yes, the lines have equal slopes.
d.
No, one line has slope, while the other has no slope.

Answer 1

Slope of first line, m = 8 - 5 / -1- 0 = -3
Slope of second line, m = 3 + 1 / 3 - 5 = 4 / -2 = -2

In short, Your Answer would be Option A) No, the lines have unequal slopes.

Hope this helps!
