Answer:
The school C shows the greatest rate of change between male and female students
Step-by-step explanation:
Let
x -----> the number of female students
y ----> the number of male students
we know that
The ratio of male students to female students is
we have
<em>School A</em>
<em>School B</em>
----> the slope of the linear equation
<em>School C</em>
so
therefore
The school C shows the greatest rate of change between male and female students
Answer:
The other midpoint is located at coordinates (-9,-2) (Second option)
Step-by-step explanation:
<u>Midpoints</u>
If P(a,b) and Q(c,d) are points in , the midpoint between them is the point exactly in the center of the line that joins P and Q. Its coordinates are given by
We are given one endpoint at P(1,-2) and the midpoint at M(-4,-2). The other endpoint must be at an equal distance from the midpoint as it is from P. We can see both given points have the same value of y=-2. This simplifies the calculations because we only need to deal with the x-coordinate.
The x-distance from P to M is 1-(-4)=5 units. This means the other endpoint must be 5 units to the left of M:
x (other endpoint)= - 4 - 5 = - 9
So the other midpoint is located at (-9,-2) (Second option)
