Answer:
m= 3/5.
Step-by-step explanation:
The general equation of the line is:
(y - y0) = m ( x - x0), where "m" represents the slope is: (y1 - y0) / (x1 - x0).
From the statement we know that (x1, y1) = (6, 8) and (x0, y0) = (1,5)
Then the slope is:
m= (y1 - y0) / (x1 - x0) = (8 - 5)/(6 - 1) = 3/5.
The slope is 3/5
