In order to be perpendicular, you must have a slope that is the opposite reciprocal, so the slope should by -3/4. So the equation could be y = -3/4x with any other number at the end.
Answer:
(a) 
-- The equation
(b) 31 inches
Step-by-step explanation:
Given
See attachment
Solving (a): The equation of the trend line.
We start by calculating the slope (m)
Where
So, we have:
The equation is then calculated using:
Where:
Open bracket
(b) The height of a 2 year old.
To do this, we substitute 2 for x in
The prediction is 31 inches
(not sure if you needed help with inserting an actual pdf or a picture) so you go to input your question like you did, but before you submit, click on the question bar where you were typing.
