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 the definition of a slope ("math") from Wikipedia:
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".
I am sure, now you can answer the question #12 on your own.
Question 13.
From the given equation -4x + 2y = -10 express y =  , or, which is the same, y = 2x-5.
Again, recall the definition above.
What is the slope?
Now, there is a rule in this site: ONE QUESTION PER POST.
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.
