Answer:
The graph with solution is shown below.
Step-by-step explanation:
We need to find the
and
for given equation.
For
, substitute 
Considering inequality sign as equality and simplifying,
, point is 
Similarly,
For
, substitute 
We get,
, point is 
We locate this two points on the graph now and join them.
The joining line will be dotted as the inequality has just 'greater than' symbol. The region above the dotted line is the solution to graph.
Answer:
The geometrical relationships between the straight lines AB and CD is that they have the same slope
Step-by-step explanation:
Given


Required
The relationship between AB, CD
Since AB is a straight line and O is the origin, then:

Where:
====> 
====>
This implies that:
So:



So, we have:


Calculate the slope (m) of 

For AB


For CD



By comparison:

This implies that both lines have the same slope
