Answer:
i think the answer is -3/4
The mediam is the "center" of an arranged rundown of numbers. The middle is the esteem isolating the higher portion of an information test, a populace, or a likelihood conveyance, from the lower half. For an informational collection, it might be thought of as the "center" esteem.
m perpendicular to q is the correct answer
The coordinates of B are 
.
Solution:
Given A(2, –1), B(x, y) and C(4, 2)
AB is a line segment C is a point on AB.
AC : CB = 3 : 1
To find the coordinates of B:
Section formula:
The point 
divides the line segment 
and 
in the ratio
m : n are 
Here, 
and m = 3, n = 1
Using section formula,
Substitute the given values in the section formula.
Equate the x-coordinates and y-coordinates.
Hence the coordinates of B are .
Y- intercept =-5
y-y1=m(x-x1)
y-(-1)=4(x-1)
y+1=4(x-1)
y+1=4x-4
y=4x-4-1
y=4x-5
Or
y=4x+b
-1=4(1)+b
-1=4+b
-1-4=b
-5=b. Y-intercept is -5
