Answer:



Step-by-step explanation:
Given

First, graph
(See attachment)
We are not limited to any particular linear equation; as long as we meet the required condition
Solving (a): Equation of a line that intersects
at two points
Select any two points on opposite sides of the curve
The selected points are:


Calculate slope (m)




The equation is then calculated using:

This gives:


Open bracket


Solving (b): Equation of a line that intersects
at one point
A good illustration of this is x-axis
Because it intersects with the line at just one point, which is origin (0,0).
The equation of line at this point is:

Solving (c): Equation of a line that does not intersect
Here, we make use of any horizontal line below the x-axis
Select any two horizontal points below the x-axis


Calculate slope



The equation is then calculated using:
