Answer:
y = 3 , x = 4 , y = 0 , x = - 3
Explanation:
• the equation of a horizontal line is
y = c ( c is the value of the y- coordinates the line passes through
• the equation of a vertical line is
x = c ( c is the value of the x- coordinates the line passes through )
A (- 3, 3 ) and B (4, 3 ) lie on a horizontal line with y- coordinates 3 , then
y = 3 ← equation of line
-----------------------------------
B (4, 3 ) and C (4, 0 ) lie on a vertical line with x- coordinates 4 , then
x = 4 ← equation of line
-----------------------------------
C (4, 0 ) and D (- 3, 0 ) lie on a horizontal line with y- coordinates 0 , then
y = 0 ← equation of line
-----------------------------------
D (- 3, 0 ) and A (- 3, 3 ) lie on a vertical line with x- coordinates - 3 , then
x = - 3 ← equation of line
