The correct answer is y=x+4.
        
             
        
        
        
Answer:
y = -1x + 3 or y = -x + 3 (**That is the last option which is D**)
Step-by-step explanation:
You need to do slope-intercept formula and the slope formula.
The Slope-Intercept Formula: y=mx+b
The Slope Formula: y2 - y1 / x2-x1
Your coordinates:
(-1,4) and (1,2)
2 - 4/1- (-1) 
-2/2 
Simplified is -1
Your "m" in the slope-intercept formula is -1
Formula: y=-1x + b
Now, you need to find the Y-Intercept which is the "b" 
Using our slope-intercept formula, you need to plug in "x1" and "y1"
4 = -1(-1) + b 
4 = 1 +b 
4-1 = b 
3 = b 
So your equation is:
y = -1x + 3 or y = -x + 3 
 
        
             
        
        
        
$29 dollars is the overall change in his account. The reason that this is correct is because if you make a number line -4 is exactly 29 units away from 25.
