Answer:


Step-by-step explanation:
Given
Let
f = Father's age
s = Son's age
We'll solve this question, while reading through the instructions
From the first statement;
f is 2 less than 7 times s.
This means

In two years time, the father will be f +2 and the son will be s + 2
So, their sum is:


Collect like terns


So, the equations are:

Step-by-step answer with explanations:
Recall that a coordinate pair such as (5,-1) has two components.
The first (5, -1) means that the point is situated at x=5.
The second (5, -1) means that the point is situated at y=-1.
Now, a <em>horizontal</em> line through (5,-1) means that ALL points on the line have y-coordinate equal to -1, so that any point with y=-1 will lie on this horizontal line. An example would be (-2,-1).
A <em>vertical</em> line through (5, -1) means that ALL points on the line have x-coordinate equal to 5, so that any point with x=5 will lie on this vertical line. An example would be (5,4).
