Suppose that a certain strain of pea plant requires 14 days to reach a height of 6 inches and 30 days to reach a height of 16 inches. Write a linear equation in slope-intercept form that models the height of the plant after x days.

Question

Suppose that a certain strain of pea plant requires 14 days to reach a height of 6 inches and 30 days to reach a height of 16 inches.  Write a linear equation in slope-intercept form that models the height of the plant after x days.

(14,6) , (30, 16)

anonymous · Answer

Alright, you have the following points:

(days, height) = (x,y) = (14,6) and (30,16)

now in order to find the equation of those lines , first find the slope :

yeh, two points , find eqn of line lol

anonymous · Answer

lol ^_^

anonymous · Answer

did you get a hint of what you're supposed to do bailey? :)

anonymous · Answer

yess (: thanks (: your the best (:

anonymous · Answer

np ^_^ good luck!

anonymous · Answer

I think your poblem was determing the points :)

anonymous · Answer

prob should explicitly say x>=0 in the solution

anonymous · Answer

to be 100% correct

anonymous · Answer

LOL , what differenece would that make? :)

anonymous · Answer

ohh it would make a difference

anonymous · Answer

could possibly take marks off for it ,

anonymous · Answer

oh .-. do that then bailey!

anonymous · Answer

i got y=5x-22/8
