Answer:
y =  x + 5
 x + 5
Step-by-step explanation:
 the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
f(x) = - 2x + 1 ← is in slope- intercept form
with slope m = - 2
Given a line with slope m then the slope of a line perpendicular to it is
 = -
 = -  = -
 = -  =
 =  , then
 , then
y =  x + c
 x + c
the line crosses the y- axis at (0, 5 ) ⇒ c = 5
y =  x + 5 ← equation of perpendicular line
 x + 5 ← equation of perpendicular line

Answer:
(a)  -- The equation
 -- 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
