Answers to numbers 2 and 3
BARSIC [14]
For both of them you just make them into fraction.
For #2
\frac{36}{120}
and then you simplify it
36. ÷12 3
-----. =. --------
120. ÷12 10
After this you want to change the fraction to a percentage.Percentage are out of 100

so you simply will multiply by 10 to the top and bottom
3. 30
----. * 10 =. -----. = 30%
10. 100

The answer is 30%

For number #3
you simply put 63 over 240
63
-----
240
63  \div 3= 21
240 \div 3 = 80
\frac{21}{80}
21
----
80
is that answer because it can't be simplified
after that

The graph of a line has a slope of -3 and passes through the point (-6,-4).
prohojiy [21]

Answer:

(A) y+4=-3(x+6)

Step-by-step explanation:

The point-slope form of the equation of a line whose slope is m and passes through the point (x_1, y_1) is: y-y_1=m(x-x_1)

Given the point: (x_1, y_1)=(-6,-4)

Slope, m=-3

x_1=-6\\y_1=-4

Substituting these values into:  y-y_1=m(x-x_1), we obtain the point slope form of the equation:

y-(-4)=-3(x-(-6))\\\\y+4=-3(x+6)

The correct option is A.
