What is the equation of the blue line?

y = -3x - 1

Step-by-step explanation:

pass (-2,5) (0,-1) (1,-4)

use any two points to find the equation

slope (m) = (-1 -5)/(0- -2) = -6/2 = -3

y = mx+b     b: y intercept=-1

equation: y = -3x - 1

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
