Answer:
For this case we have that the trend line goes through the following points:
"A line of best fit passes through the y-axis at 1 and through the point 4 and 3"
That is, it goes through:
(0, 1)
(4, 3)
The equation of the line is:
y = mx + b

Where,
b = 1

The slope is:
m = (y2-y1) / (x2-x1)
 
 m = (3-1) / (4-0)

 m = (2) / (4)

 m = 1/2
Substituting values:
y = (1/2) x + 1

Answer:
The equation of this line of best fit in slope-intercept form is:
y = one halfx + 1
