The slope of a line that goes through -3 -5 and -3 -6 is what

positive
negatative***
zero
undefined

the x-coordinate is constant, but the y-coordinate changes

what does the slope equation (m = ?) tell you?

btw, point are written in the form

(-3,-5) and (-3,-6)

your answer is incorrect.
As Scott suggested, you have a vertical line.
Horizontal lines have zero slope,
Vertical lines have .......

To find the slope of a line passing through two points, we can use the formula:

slope = (y2 - y1) / (x2 - x1)

In this case, the given points are (-3, -5) and (-3, -6). Let's substitute the coordinates into the formula:

slope = (-6 - (-5)) / (-3 - (-3))
= (-6 + 5) / (-3 + 3)
= -1 / 0

Since the denominator is 0, the slope is undefined. Therefore, the correct option is "undefined," not negative.
