The average height of a 5-year old
girl is 44 inches, and the average
growth rate per year is 2.4 inches.
Write an equation in point-slope form
that describes the height of a girl y
based on her age x.
Select one:
a. y - 2.4 = 44(x-5)
b. y - 44 = 2.4(x-5)
c. y - 5 = 2.4(x-44)
d. y - 44 = 5(x-2.4)

jim_thompson5910 · Answer

point slope form is 

y-y1 = m(x-x1)

jim_thompson5910 · Answer

m is your slope

(x1,y1) is the point that the line goes through

jim_thompson5910 · Answer

so what is your slope in this case?
