Answer:
y = 3x + 62
Step-by-step explanation:
Using the points :
(0, 62) and (6, 80)
Equation of trend line is in the form:
y = mx + c
Where m = slope ; c = intercept
Slope (m) = (y2 - y1) / (x2 - x1)
m = (80 - 62) / (6 - 0)
m = 18 / 6
m = 3
Intercept, c = value of y when x = 0
From (0, 62)
x = 0 ; y = 62
Then c = 62
Hence,
y = 3x + 62
