SOLUTION
The formula for the equation of a line is,
[tex]y=mx+b[/tex]
From the question, we are to multiply the value of x by 3.
Therefore,
[tex]m=3[/tex]
Which will then give us,
[tex]y=3x[/tex]
And finally, we are to subtract 6 from the result to get the value of y
Therefore,
[tex]b=-6[/tex]
Which will become,
[tex]y=3x-6[/tex]
Hence, the equation in terms of x and y is
[tex]y=3x-6[/tex]
Therefore, the graph of the function is
