Find the slope of the line passing through the pair of points, if possible. (If an answer is undefined, enter UNDEFINED.)
P(4, 7); Q(8, 23)
as usual, the slope of PQ is
Δy/Δx = (23-7)/(8-4) = 16/4 = 4
To find the slope of the line passing through the pair of points P(4, 7) and Q(8, 23), you can use the slope formula:
m = (y2 - y1) / (x2 - x1)
Let's plug in the values of the coordinates:
m = (23 - 7) / (8 - 4)
Simplifying:
m = 16 / 4
m = 4
Therefore, the slope of the line passing through the points P(4, 7) and Q(8, 23) is 4.
