Answer:
D. -1
Step-by-step explanation:
We have been given a set of data points and the slope of the line of best fit as 2.5.
The equation of the line of best fit, in slope-intercept form, can be thus written as;
y = 2.5x + c
where c is the y-intercept of this line.
We can then use any of the points given to determine c. Using the point
( 2, 4);
4 = 2.5(2) + c
4 = 5 +c
c = 4-5 = -1
