Answer:
Step-by-step explanation:
To find the coordinates of the point is 1/4 of the way from A (-6, -3) to B (6, 1), we are going to be using the midpoint formula, which states that:
The midpoint is at . Where:
Then, the midpoint is at:
=
Now, to find the coordinates of the point that is 1/4 of the way, we are going to calculate the midpoint between the point 'A' and the midpoint previously caculated, as follows:
⇒ =
Therefore, the point is 1/4 of the way from A to B is:
Answer:
y=
Step-by-step explanation:
Perpendicular lines have negative reciprocal gradients(slopes) so the slope of your new line would be 1/2. Then you use the point to find the new y-intercept
y=mx+b
2=(8)+b
2=4+b
B=-2
y=
This is equivalent to finding a function g in which 
.
We simply reverse the actions of the initial function by adding 81 back and taking the square root. Therefore,
