Answer:
Point (-5,21) would end up in quadrant II (2).
Step-by-step explanation:
It would end up in quadrant 2 because x=-5 which means it would go left.
y=21 which means it would go up.
Because of this, the point would end up in the top left of the graph which is quadrant 2.
 
        
             
        
        
        
Answer:

Step-by-step explanation:
Slope intercept form of a line is given by:

Where 
m is the slope and b is the y-intercept
Given slope is  
We can write:

Now to find b, we replace x with -3 and y with -4, given, so we have:

So, the equation is:

Now,
The standard form is given by:

So, we take x and y to left side and the constant to right side. Rearranging, we get:

The first answer choice is right.
