Answer:
y=3x+17
Step-by-step explanation:
Slope formula y2-y1/x2-x1=m
y=3x+b
Find b (y-intercept), enter the given coordinates (-3, 8)
8=3(-3)+b
8=-9+b
b=17
y=3x+17

Answer:
D.  d = sqrt( ( x2-x1)^2 + (y2-y1)^2)
C.   d = sqrt( ( x1-x2)^2 + (y1-y2)^2)
B.  d = sqrt( (|x2-x1|^2 + |y2-y1|^2)
Step-by-step explanation:
Given two points (x1, y1) and (x2,y2)  we can find the distance using
d = sqrt( ( x2-x1)^2 + (y2-y1)^2)
The order of the terms inside the square doesn't matter
 d = sqrt( ( x1-x2)^2 + (y1-y2)^2)
When we are squaring are term, we can take the absolute value before we square and it does not change the value
d = sqrt( (|x2-x1|^2 + |y2-y1|^2)
 
        
             
        
        
        
Let's say Bailey takes "b" days to paint it.
and Andrew takes "a" days to paint the same house.
now, Andrew is 6 times faster than Bailey, therefore, if Andrew takes "a" days to do it, Bailey takes then "6a" days, or b = 6a.
now, the year they worked together, they finished it in 7 days.
so, after 1 day then, they have only done 1/7 of the whole work.
and Andrew for one day, has done 1/a of the house, whilst Bailey has done 1/b of the house or 1/(6a).

 
 
        
        
        
The power of two is any number squared.
