Hello :
the line has an undefined slope if paralel a axis- y : equation x = 1 (<span>passes through the point (1, 3))</span>
The rate of change is +2
as an ordered pair it would be (1,-3),(2,-1)(3,1),(4,3)
The area is 289.22 units squared
Y = 5
i think that what you meant
so the point will be (0,5) and will be a horizontal line at y=5
hope that helps
