Answer:
C
Step-by-step explanation:
original formula is: y - y1 = m (x - x1) ordinates= (x1, y1)
insert the a corresponding x and y coordinate:
y + 3 = -2 (x + 9)
Don't forget to change the signs depending on whether their positive or negative:
(3, -9) since 3 is positive but there is a minus in the formula it would be -3
since -9 is negative and in the equation there's a minus sign you would change it to positive. (negative times a negative equals a positive)
The answer is: b - lies in quadrant II when graphed.
Explanation:
Any number less than zero is a negative number.
Example: -1
Any number greater than zero is a positive number.
Example: 1
(a, f(a))
(-1,1)
When these example points are graphed, they are placed in the second quadrant.
There would be 12 girls and 18 boys. Since the ratio is 2:3, there are 5 parts total (2+3=5) With 30 students, each part equals 6 students (30/5=6) Therefore the two parts that are girls would be 6 x 2, or 12 students, leaving the remainder of students, 18, to be boys

Answer:
a ">"
Step-by-step explanation:
3 to the power negative one (-1) is the same as 1/3 (one unit divided by 3).
1/4 on the other hand is one unit divided by 4.
Dividing one object into three parts (think for example a chocolate bar) gives you a larger (greater) piece than dividing it into four equal pieces.
Therefore 1/3 > 1/4
