Answer:

a) y = 1/4x + 4

b) 4.625 inches

Explanation:

a) y(0) = 4 inches

slope = 1/4 rate

y = 1/4x + 4

b) 12:00pm (noon) to 2:30pm = 2 hours 30 mins = 2.5 hours

y = 1/4x + 4

y = (1/4)(2.5) + 4

y = 0.625 + 4

y = 4.625 inches

Answer:

Explanation:

they say by noon 4 inches of rain has fallen, then the say that it's falling at 1/4 inch per hour

f(x) = 1/4x +4

where x is in hours, and f(x) represents the linear graph of the amount of rain that has fallen after noon :)

so by 2:30 or 2.5 hours.... then

f(2.5) = 1/4x +4

y = 1/4 (2.5) +4 ( i moved to the y b/c now there is an answer)

y =
(5)/(8) + 4

y =4
(5)/(8) inches of rain
