Answer:
4
Step-by-step explanation:
(y1-y2)/(x1-x2) = (2-10)/(1-3) = -8/-2 = 4
Answer:
35.25
Step-by-step explanation:
Answer:
0.1
Step-by-step explanation:
(9,4) (5,1)
, plug in the numbers,
=
, to write it as a decimal, you divide the numerator by the denominator, 0.1
Compute the slope of the line through (-2, -9) and (-4, -17):
![\dfrac{-9-(-17)}{-2-(-4)}=\dfrac82=4](https://tex.z-dn.net/?f=%5Cdfrac%7B-9-%28-17%29%7D%7B-2-%28-4%29%7D%3D%5Cdfrac82%3D4)
Any line perpendicular to this line will have slope -1/4. The one that passes through (0, 10) satisifes
![y-10=-\dfrac14(x-0)\implies\boxed{y=10-\dfrac x4}](https://tex.z-dn.net/?f=y-10%3D-%5Cdfrac14%28x-0%29%5Cimplies%5Cboxed%7By%3D10-%5Cdfrac%20x4%7D)
