Answer
Substitute w by 7 
7^3 
7x7x7 =343
        
                    
             
        
        
        
67 divided by 19 equal 3.52631578947
hope this help
        
                    
             
        
        
        
Point-slope form of a line: We need a point (x₀,y₀) and the slope "m";
y-y₀=m(x-x₀)
We have the next equation of line:
y=1/2 x-2  (slope-intercept form y=mx+b)
the slope of this line is 1/2  (m=1/2)
And any one point could be:
if x=0; then y=1/2 (0)-2=-2  (0,-2)
Therefore, we already have the point (0-,2) and the slope (m=1/2)
y-y₀=m(x-x₀)
y+2=1/2(x-0)
Answer: the point slope form of y=1/2 x-2; would be:
y+2=1/2(x-0)
