Answer:
Just substitute "x" with "3".
Step-by-step explanation:
y = 2.4x + 3.1
y = 2.4(3) +3.1
y = 7.2 + 3.1
y= 10.3
Answer: 10.3 minutes
(0,7) and (2,4) go to slope =-3/2
(1,-3) and (-1,-3) go to zero slope
(0,0) and (2,1) go to slope =1/2
(0,-1) and (2,-5) go to slope =-2
and (-1,3) and (-1,-3) go to no slope
