Question 909698: Suppose the weights (W) of male student in MA102 are linearly related to their heights (h). If a student 150 cm tall weights 70kg, and a student 165 cm tall weights 110kg. a) write an equation to express weight in terms of height. B) If there is a student with 90kg weight, how tall is this student?
Answer by josmiceli(19441) (Show Source): You can put this solution on YOUR website!
I will plot height (h) on the horizontal axis and
I will plot weight (W) on the vertical axis
-----------------------------------
You are given 2 points:
( 150, 70 ) and
( 165, 110 )
--------------
(a)
You can use the general point-slope formula:

Multiply both sides by

-------------------
check the answer:

OK
---------------
(b)

The student weighs 157.5 kg
