Answer:
Step-by-step explanation:
We have been given an image of a line segment and we are asked to find the equation of perpendicular bisector of our given line segment in slope-intercept form.
Since we know that the slope of perpendicular line to a given line is negative reciprocal of the slope of the given line.
Let us find the slope of our given line using slope formula.
, where,
= Difference between two y-coordinates,
= Difference between two x-coordinates of same y-coordinates.
Upon substituting the coordinates of points (2,4) and (4,-2) in slope formula we will get,
Now we will find negative reciprocal of 
to get the slope of perpendicular line.
Since point (3,1) lies on the perpendicular line, so we will substitute coordinates of point (3,1) in slope-intercept form of equation 
.
Therefore, the equation of perpendicular line will be 
and option A is the correct choice.
The correct answer on how Marcelina does this expenses is that Marcelina spends the intended amount of money and buys more than the intended amount of corn.
<h3>How to check the expenses that Marcelina made</h3>
The numbers at point C are 20,50.
What she is supposed to buy are
30 white corn and 20 yello maize
20 + 50 = 70kg
This has shown that Marcelina has bought more than the amount of corn that she is supposed to buy.
Meanwhile what she was supposed to get was 50 kg.

Answer:
The y-coordinate of their intersection point is 3
That is y=3
Step-by-step explanation:
Given two lines are y=6x+15 and y=mx+4
Given that the two lines intersect at x=-2
To find the y coordinate of their intersection point :
Equating the two lines
6x+15=mx+4
6x+15-mx-4=0
6x-mx+11=0
(6-m)x+11=0
At x=-2 (6-m)x+11=0
(6-m)(-2)+11=0
(6-m)(-2)=-11
Substitute the value in y=mx+4 we get
At x=-2 
Therefore y=3
Therefore the y-coordinate of their intersection point is 3
