Answer:
11. Slope of the line is 7/10.
12. Slope of the line is ![-\frac{1}{3}](https://tex.z-dn.net/?f=-%5Cfrac%7B1%7D%7B3%7D)
Step-by-step explanation:
11. Given points are:
(-6, 1) and (4, 8)
Slope of a line is given by the formula;
m = ![\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
m = ![\frac{8-1}{4-(-6)}](https://tex.z-dn.net/?f=%5Cfrac%7B8-1%7D%7B4-%28-6%29%7D)
m = ![\frac{7}{4+6}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B4%2B6%7D)
m = ![\frac{7}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B10%7D)
Slope of the line is 7/10.
12. Given points are:
(2, -3) and (5, -4)
Slope of the equation is;
m = ![\frac{-4-(-3)}{5-2}](https://tex.z-dn.net/?f=%5Cfrac%7B-4-%28-3%29%7D%7B5-2%7D)
m = ![\frac{-4+3}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B-4%2B3%7D%7B3%7D)
m = ![\frac{-1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B-1%7D%7B3%7D)
Hence,
Slope of the line is
.

Answer: is it supposed to be 2y+y=4?
Answer:
3 9/10
Step-by-step explanation:
First the "whole number" part is 3.
The decimal part is 0.9. To convert that, keep the 9. Since the 9 is in the tenths place, it is 9/10.
Add them together: 3+9/10= 3 9/10
Final answer 3 9/10
