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