Answer:
Option B is correct
Function 1, because the slope is 4 and the slope of function 2 is 2.	
Step-by-step explanation:
Slope-intercept form:
The equation of line is given by:

where, m is the slope and b is the y-intercept
As per the statement:
Function 1: y = 4x + 5
On comparing with [1] we have;
Slope of function 1  = 4
Function 2: The line passing through the points (1, 6) and (3, 10).
Using slope formula:

Substitute the given points we have;

⇒
Simplify:
⇒
⇒
⇒ Slope of the function 2 is, 2
Since, function 1 is greater rate of change.( i.e 4 > 2)
Therefore, 
Function 1  has the greater rate of change,  because the slope is 4 and the slope of function 2 is 2.

Ratio of areas of similar triangles is 9 : 25.
Solution:
Given data:
Ratio of sides of two similar triangles = 3 : 5
To find the ratio of areas of the triangles:
We know that,
<em>In two triangles are similar, then the ratio of their area is equal to the square of the ratio of their sides.</em>

                       
                       
Ratio of areas of similar triangles is 9 : 25.
