Question

practice write the equation for each graph. 3. line 3 4. line 4

Explanation:

Step1: Recall line - equation forms

For a vertical line, the equation is of the form $x = a$ (where $a$ is the $x$ - coordinate of all points on the line), and for a horizontal line, the equation is of the form $y = b$ (where $b$ is the $y$ - coordinate of all points on the line).

Step2: Analyze line 1

Line 1 is a vertical line passing through $x = 2$. So its equation is $x=2$.

Step3: Analyze line 2

Line 2 is a vertical line passing through $x=- 4$. So its equation is $x = - 4$.

Step4: Analyze line 3

Line 3 is a horizontal line passing through $y = 3$. So its equation is $y = 3$.

Step5: Analyze line 4

Line 4 is a horizontal line passing through $y=-2$. So its equation is $y=-2$.

Answer:

Line 1: $x = 2$
Line 2: $x=-4$
Line 3: $y = 3$
Line 4: $y=-2$
