Question

raquel throws darts at a coordinate grid centered at the origin. her goal is to create a line of darts. her darts actually hit the coordinate grid at (-5,0), (1,-3), (4,5), (-8,-6), (0,2), and (9,6). which equation best approximates the line of best fit of the darts?
o y = 0.6x + 0.6
o y = 0.1x + 0.8

o y = 0.5x + 0.6

Explanation:

Step1: List data and compute sums

n=6; Σx=-8, Σy=4, Σxy=65, Σx²=106

Step2: Calculate slope (m)

m=(665 - (-8)(4))/(6106 - (-8)²)=422/572≈0.74

Step3: Estimate closest option

0.74 is closest to 0.6 (options: 0.6,0.1,0.2,0.5)

Answer:

A. y = 0.6x + 0.6
