what is the slope of the line that goes through (-3, -5) and (-3, -6) NEED THIS DONE SOON HELP PLEASE! SORRY ALL CAPS

Answer 1

(Y2-Y1)/(X2-X1)
(-6 +5) / (-3 + 3)
-1/0 undefined, vertical straight up and down,
x = -3 is the equation of the line

Answer 2

If you sketch/graph the two points you can see that it is a vertical line : ) thus an undefined slope.
