Answer:
b = 5
Step-by-step explanation:
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = C(1, 3) and (x₂, y₂ ) = D(4, - 3)
m = 
= 
= - 2, hence
y = - 2x + b ← is the partial equation of the line
To find b substitute either of the 2 points into the partial equation
Using (1, 3), then
3 = - 2 + b ⇒ b = 3 + 2 = 5

Step-by-step explanation:
so, the 200m winner's average speed was
200m/(60+57)sec = 200/117 m/s
so, 400m with the same speed would need x seconds :
200x/117 = 400
200x = 400×117
x = 2×117 = 234 seconds = 3 minutes and 54 seconds
(after seeing that a minute has 60 seconds, and that then 234/60 = 3 and 54 remainder).
so, she would have reduced her time by 10 seconds (from 4 minutes 4 seconds down to 3 minutes 54 seconds = 4 + 6 = 10).
