Answer:
Answer is D
Step-by-step explanation:
The slope of the line that passes through (5,−10) and ( 11 , − 12 ), in simplest form is: -1/3
<em><u>Recall:</u></em>
- The slope of a line passing across through two points can be calculated using:
![m = \frac{y_2 - y_1}{x_2 - x_1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D)
<em><u>Given two points:</u></em>
(5,−10) and ( 11 , − 12 )
![(5,-10) = (x_1, y_1)\\\\( 11 , - 12) = (x_2, y_2)](https://tex.z-dn.net/?f=%285%2C-10%29%20%3D%20%28x_1%2C%20y_1%29%5C%5C%5C%5C%28%2011%20%2C%20-%2012%29%20%3D%20%28x_2%2C%20y_2%29)
![m = \frac{-12 - (-10)}{11 - 5}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B-12%20-%20%28-10%29%7D%7B11%20-%205%7D)
Slope (m) = -2/6
Slope (m) = -1/3
Therefore the slope of the line that passes through (5,−10) and ( 11 , − 12 ), in simplest form is: -1/3

Answer:
(a) x - y + 1 = 0
Step-by-step explanation:
One way to address multiple-choice questions is to try the answers to see what works.
For the lower left point (1, 2), the answer choices shown give ...
x -y +1 = 1 -2 +1 = 0 . . . . . equation works
-x -y +1 = -1 -2 +1 = -2 . . . doesn't work
y -x +1 = 2 -1 +1 = 2 . . . . . doesn't work
The appropriate choice is ...
x - y + 1 = 0
