Question
The inequality, x ≤ 2, will make ________________ type of line.
- Vertical Dashed
- dashed solid
- vertical solid
- Horizontal solid
Hint:
In this question, we have to find the inequality , x<=2 will make __ type of line. To graph an inequality, treat the <, ≤, >, or ≥ sign as an = sign, and graph the equation. If the inequality is < or > line is dashed or if there ≤ or ≥ then the line solid on the graph.
The correct answer is: vertical solid
Here we have to find the inequality , x<=2 will make __ type of line .
Firstly , if If the inequality is < or > line is dashed or if there ≤ or ≥ then the line solid on the graph.
Here, we have x ≤ 2 , so it has a solid line because the value is included.
And the graph is less than 2 on x-axis then, it is going to the vertically.
Therefore, The inequality, x ≤ 2 , will make vertical solid type of line.
The correct answer is vertical line.
Since the inequality symbol is ≤, the boundary line will be thick/solid and the portion below the line will be shaded.
The inequality, x ≤ 2, will make vertical solid type of line.
In this question, we have to given inequality on graph and we have to find the which type of line it has. For that always remember, To graph an inequality, treat the <, ≤, >, or ≥ sign as an = sign, and graph the equation. If the inequality is < or > line is dashed or if there ≤ or ≥ then the line solid on the graph.
