Question

What is the slope of the line parallel to a line that passes through the points L(0, 5) and Q(4, -5)

Answer 1

Answer:

5/2

Step-by-step explanation:

As we go from point L(0, 5) to point Q(4, -5), x increases by 4 and y decreases by 10.  Thus, the slope of this line is m = rise / run = 10/4, or m = 5/2.  This 5/2 is also the slope of any line parallel to this one.

Answer 2

B

Using 2 points (x1,y1) (x2,y2): Slope is defined as (y2-y1)/(x2-x1)

So in this case (-5-5)/(4-0) = -10/4 which simplifies to -5/2 or B
