a linear equation is given by the formula:
In the equation y = 0 , the terms m and b are equal to zero
Y = 0x + 0
Then, a parallel equation to y = 0 has the same slope m = 0
y = 0*x + b
y = b
The equation passes through (-7,4), if we replace into the equation above, we get:
y = 0*(-7) + 4
y = 4
Answer: The equation y = 4 is parallel to y = 0 and passes through (-7,4)
