12.	Find the slope of the graph of the equation  y = 3x - 4
13.	Find the slope of the graph of the equation -4x + 2y = -10
14.	Find the x and y intercepts of the graph of the equation -3x + 2y = 78.  Find the intercepts algebraically and show your work on your work paper.

Question 12.

Since you ask in #12 "Find the slope of the graph of the equation  y = 3x - 4", I conclude that you don't know what is the slope.


So, in response I send you <A HREF=https://en.wikipedia.org/wiki/Slope>the definition of a slope</A> ("math") from Wikipedia:


<pre>
    In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. 
    Slope is often denoted by the letter "m" in the equation of a straight line "y = mx + c".
</pre>

I am sure, now you can answer the question #12 on your own.



Question 13.
From the given equation  &nbsp;-4x + 2y = -10  &nbsp;express  &nbsp;y = {{{(-10+4x)/2}}}, &nbsp;or, &nbsp;which is the same,  &nbsp;y = 2x-5.

Again, recall the definition above.
What is the slope?



Now, there is a rule in this site: <U>ONE QUESTION PER POST</U>.


If you ask too many questions in one post, there is a risk you do not get the answer at all.


It is not because we, tutors, are bad men and women.
It is because "s'est la vie".


It is because if I answer all your questions in one post, you will lose the line.


By the way, it is the rule of writing business letters, too:
"One subject in one letter", if you want to get the answer.
