To solve inequality and graph its solution.
Explanation of Solution
Given information:
Inequality
Graph:
Calculation:
Write in slope intercept form
1)
Ordinary line
2)
Y-intercept: (0,0)
Substituting x=0 in equation (2)
Then, y=0
Substituting x=2 in equation (2)
Then, x=-5
Table of x and y is given below
x | y |
0 | 0 |
2 | -5 |
The graph of ordinary equation
For finding region
Point (1, 1) is above line
Substituting value of point (1, 1) in inequality equation (1)
On solving,
is not true
Point (-1,-1) is below line
Substituting value of point (-1,-1) in inequality equation (1)
On solving,
This is true
Then region is below line
The graph of inequality is given below
Solution set: {(-1,-1) , (-2,-2) , (-3,-3)}
