Answer:
(a) (4,9), (8,14).; (b) 1.25 in/h; (c) d = 1.25h + 4 ; (d) 4 in; (e) 19 in
Step-by-step explanation:
(a) Information as coordinate pairs
4 h, 9 in ⟶ (4, 9)
8 h, 14 in ⟶ (8,14)
The coordinates of the two points are (4,9), (8,14).
(b) Slope of the line
The slope of the line is 1.25 in/h
(c) Equation of the line
The y intercept is at (0,4)
d = 1.25h + 4
(d) Depth when snowfall began
The depth was 4 in when the snowfall began.
(e) Depth after 12 h
The depth would be 19 in after 12 h.
The figure below is a graph of your function. It shows that the depth was 4 in at the start of the snowfall, that it increases by 5 in every 4 h, and predicts a depth of 19 in after 12 h.
