Find the equation of the line passing through (-9,11),(-9,14)

show work please

delta y / delta x
y2-y1/x2-x1
14-11/-9-(-9)
slope is undefined
3/0 = undefined

therefore, equation of line does not exist. Unless is vetical x=-9

Y=x+3 between 11 and 14 is 3 and -9 and -9 is 0 making your slope undefined and since u state the x and y which is 0,3

The x value does not change so the equation is that of a vertical line:
x = -9

Both points contain -9 for x so you could use x=-9
