Question

the equation for the line of best fit is y = 1.5x + 0.25. based on the equation, which of these statements is true? a scarf with 7 colors would likely take about 14 hours to knit. a scarf with 6 colors would likely take about 9 hours to knit.

Explanation:

Step1: Substitute x = 7 into the equation

$y=1.5\times7 + 0.25=10.5 + 0.25 = 10.75$ (not about 14 hours)

Step2: Substitute x = 6 into the equation

$y=1.5\times6+0.25 = 9 + 0.25=9.25\approx9$ (about 9 hours)

Answer:

A scarf with 6 colors would likely take about 9 hours to knit.
