Answer: 22/9
Step-by-step explanation :slope of a trend line that passes through the points (1, 3) and (10, 25) is 22/9
Formula of slope(m) for two points is given by:
slope m: y^2-y^1/x^2-x^1
Given the two points:
(1,3) and (10,25)
Substitute these points in the given formula we have;
m= 25-3/10-1
Simplify:
m= 22/9
Therefore, the slope of a trend line that passes through the points (1, 3) and (10, 25) is 22/9
