A basketball coach plotted data about her shooting guard’s playing time and point scoring in a scatterplot.

Shooting Guard Minutes Played and Points Scored

A graph has minutes played on the x-axis, and points scored on the y-axis. A line goes through points (8, 6) and (30, 21).

Which is the equation of the line of best-fit?
y = StartFraction 15 Over 22 EndFraction x + StartFraction 6 Over 11 EndFraction
y = StartFraction 15 Over 22 EndFraction x + StartFraction 43 Over 11 EndFraction
y = StartFraction 22 Over 15 EndFraction x minus StartFraction 86 Over 15 EndFraction
y = StartFraction 22 Over 15 EndFraction x minus four-fifths
