Answer:
   y = 4/5x +13/5
Step-by-step explanation:
The slope is given by the formula ...
   m = (y2 -y1)/(x2 -x1)
   m = (5 -1)/(3 -(-2)) = 4/5
The y-intercept is given by the formula ...
   b = y -mx . . . . for any point (x, y)
   b = 1 -(4/5)(-2) = 1 +8/5 = 13/5 . . . . using the first point
So, the equation is ...
   y = mx +b
   y = 4/5x +13/5

<em>Additional comment</em>
If you have a bunch of these to do, you may want to make a spreadsheet with the formulas built in. Then you can type in the two points and have it spit out the m and b for your equation. Even if you don't use it to <em>do</em> the work, you can use it to <em>check</em> the work.
 
        
             
        
        
        
<span>Carol noticed that 7/10 of the children playing soccer were girls. Which statement could be correct?
A. There were 28 girls and 12 boys playing soccer.
28 : x% = 40 (the total number of children) : 100%
40x = 28 * 100
40x = 2800
x = 2800 / 40
x = 70%
There were 70% of girls in the class.
70 / 100 = 0.7
7/ 10 = 0.7
This is why A is the correct answer.

Answer:
Step-by-step explanation:
Part A.
Expression  = 10
 = 10
Because 100 =  and
 and ![[(10)^2]^{\frac{1}{2}}=10^1=10](https://tex.z-dn.net/?f=%5B%2810%29%5E2%5D%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D%3D10%5E1%3D10)
[Since,  ]
]
Part B.
When simplified, the answer is RATIONAL.
[Since, 10 can be written as  ]
