Answer:
Graph
--- Slope intercept form
--- Standard form
Points
--- Slope intercept form
--- Standard form
Explanation:
Solving (a): The graph.
From the graph, we have:


First, calculate the slope

This gives:



The slope intercept equation is:

So, we have:



In standard form:

Add x to both sides


Solving (b): The points
From the graph, we have:


First, calculate the slope

This gives:



The slope intercept equation is:

So, we have:



In standard form:

Subtract 2x from both sides
