Which choice represents the equation for the line of best fit for the data shown in the table and graph?

Answer: d y = x + 12.14

explanation:
the first point starts above 10 on the y axis so it should have a y intercept higher than 10.
right away, you can eliminate choice b because it has no y intercept.

the next step is find the slope of two points.
slope is change y over change in x
for the first two points:
=> (15-3)/(13-1
=> 12/12 = 1

for the next two points
=> (18-9)/(14-5)
=> 9/9 = 1

so your slope is 1. choice d has a slope of 1. you can also see that choice c is unrealistic before doing this because it’s slope is 12, which is super high.
