21. Plot the graphs of the given equations.
a) y = x-2 b) y = 2x – 8

                            Plot the graphs of the given equations.

Part a)

Given the equation

Determining x-intercept:

So x-intercept is (2, 0)

Determining x-intercept:

So y-intercept is (0, -2)

Also

The graph of the equation is attached below, where red line indicates the graph of the equation .

Part b)

Given the equation

Determining x-intercept:

So x-intercept is (4, 0)

Determining x-intercept:

So y-intercept is (0, -8)

Also

The graph of the equation is attached below, where blue line indicates the graph of the equation .

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
