-1/3 is the slope of the line perpendicular to k
There can be 4 or 1 possible combinations of zeros
Answer:
94
Step-by-step explanation:
The triangle is split into two similar triangles. They have the same shape but not the same size. To solve, write a proportion to find KY.
Cross multiply to solve for KY.
95.2(KY) = 168(34)
95.2KY = 5,712
KY = 60
Add KY to 34 to find x.
60 + 34 = 94.

The coordinates of D are (-3, -7)
First we need to find the coordinates of B. In order to do that we simply take the average of the two points that make up the segment for which it is the midpoint (A and C).
Average of x's
-9 + -1 = -10/2 = -5
Average of y's
-4 + 6 = 2/2 = 1
Therefore, the coordinates of B are (-5, 1).
Now we can find D by noting the E will be the average of B and D. So we can use the average equation to determine the values of D.
Average of x's
(B + D)/2 = E
(-5 + D)/2 = -4
-5 + D = -8
D = -3
Average of y's
(B + D)/2 = E
(1 + D)/2 = -3
1 + D = -6
D = -7
Now we know the coordinates of D to be (-3, -7)
You can type that equation into a grphing calculator and get the table for from there or you can use desmos graphing calculator site and type in your equation to the column then hit the little settings icon and choose convert to table !!!
