The point slope form of equation through given points is:

Step-by-step explanation:
Given points are:
(x1,y1) = (-5,4)
(x2,y2) = ((1,6)
First of all we have to find the slope of line
So,

Point-slope form is given by:

Putting m=1/3

Putting (1,6) in the equation

Answer:
(a) The constant of proportionality is 0.25
(b) 1 apple = $0.25
(c) $3 = 12 apples
Step-by-step explanation:
Given

Solving (a): The constant of proportionality;
For an equation:

Where
k = constant of proportionality
By comparing:
to 

Hence, the constant of proportionality is 0.25
Solving (b): What information does
gives.
It represents the unit rate.
<em>So, it means that 1 apple costs $0.25</em>
<em></em>
Solving (c): Number of apples for $3.
This means that 
Substitute 3 for c in 

Make n the subject
