To get the slope, we will need two points that belong to the line.
From the graph, we can get two points as follows:
(0,-1) and (-1,1)
The slope of the curve can be calculated using the following rule:
slope = (y2-y1) / (x2-x1)
Substitute with the two points to get the slope as follows:
slope = (1--1) / (-1-0) = (2) / (-1) = -2

Answer:
Step-by-step explanation:
hello :
note :
for all x in ℝ : 1) sin(x+2kπ) = sinx ...k in Z 2) sin(-x) = -sinx
in this exercice :
sin(-4π-x)= sin(-x) = -sinx because : -4π = 2(-2)π (form : 2kπ when : k=-2)
Answer:
Step-by-step explanation:
<u>Given system of linear equations: </u>
---
- x + 4 = -3x - 8
- x + 3x = - 8 - 4
- 4x = -12
- x = -3
Then
Solution is (-3, 1)
Correct option is A
