The points (4, -17) and (8, r) lie on a line with slope 5. Find the missing coordinate r.

The missing coordinate, 'r', is 3

Step-by-step explanation:

The given parameters of the two points are;

The coordinates of the given points = (4, -17) and (8, r)

The slope of the line on which the two points lie, m = 5

The formula for finding the slope of a line is given as follows;

Therefore, we have;

5 × 4 = r + 17

r = 20 - 17 = 3

r = 3
