Equation of a line passing through two points (a,b) and (c,d) is given by:-

Given: x= number of square inches knitted on the scarf
y= number of yarns remaining on the ball of yarn
The equation of a line passing through (15, 300.2) and (26, 177.88):

To find initial point, put x=0

Hence, Paula starts with 301.5 yarns.

Answer:
540°
Step-by-step explanation:
90 revolutions = 360°×90 = 32400°
32400° in 60 sec or 1 min
so, in 1 sec 32400/60 = 540°
