Step-by-step explanation:
Answer:
y = (7/4)(x -4) +12
Step-by-step explanation:
The rate of growth is ...
(19 in -12 in)/(8 wk -4 wk) = 7/4 in/wk
Using this slope in a point-slope form of the equation for a line, we get ...
y = m(x -h) +k . . . . . line with slope m through point (h, k)
y = (7/4)(x -4) +12 . . . . . line with slope 7/4 through the point (4 wk, 12 in)
The correct answer to this question is 9. This can be worked out due to
the fact that 1/10 of 900 is 90, so to reach 90 you have to times 9 by
10.
