Answer:
5.98
Step-by-step explanation:
 
        
             
        
        
        
The result is 1/3.
_____
The first attempt in the attached picture has parentheses in the wrong place for the second term. This simplifies to
.. (-5/-3)*(-4) +(10 -3)
.. = -20/3 +7
.. = -(6 2/3) +7
.. = 1/3
 
        
        
        
Slope=rise/run
slope=(y2-y1)/(x2-x1) if you have the points
(x1,y1) and (x2,y2)
we have the points (-1,3) and (4,-7)  
x1=-1
y1=3
x2=4
y2=-7
slope=(-7-3)/(4-(-1))=-10/5=-2
answer is D
        
             
        
        
        
Answer: b. Y= -6/5x + 6/5 
First find the slope of your two points, then write your equation in point-slope form. Using your equation in point-slope form, you can solve and convert it to slope-intercept form.
 
        
             
        
        
        
y = mx + b
m: slope
b: y-intercept
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3x + 9y = 18
-3x            -3x
9y = -3x + 18
/9           /9
y = -3/9x + 2   OR  y = -1/3 + 2
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
m = -3/9 OR -1/3
b = 2
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
