slope is the tangent of the angle that line pases so draw one vertical line and one horizontal line to connect these points
tangent= opposite / adjacent
now opposite = the height of the vertical line
adjacent = the height of the horizontal line
or
slope of the two known points = (y2-y1)/(x2-x1)
but in this case it is not a number since 3-3 =0
14/0
it seems like no slope also tan(90) is not a number

The slope is undefined because it is parallel to the y-axis (meaning it goes up and down or is a vertical line). If it was horisontal or parallel to the x-axis the slope would be infinity. We know this because the equation to find slope between any given two points is m = (y1 - y2) / (x1 - x2). [Note that m = slope and the numbers 1 and 2 denote the different pairs of coordinate points, not multiplication.] So in this case the top of the equation would be -5 - 9 equals -14 and the bottom would be 3 - 3 equals 0. Any fraction with zero as the denominator is undefined because you can not mathematically divide by zero.

Slope is infinity and the line is parallel to y axis and cuts the x-axis at x = 3

Your line is actually a vertical line, ie, parallel to the y-axis.
Vertical lines have infinite gradients. So your slope = infinity

the line will pass though the x-axis and is parallel to y axis. The slope is not-defined.

no slope. its a line
