Gradient (or grade) is a word sometimes used for what we call the "slope" of a line.
We define slope as the ratio of the increase in the y-coordinate (sometimes called rise or y)
and the increase in the x-coordinate (sometimes called run or x).
I plotted the points and drew the segment AB in red. I colored the run blue and the rise green.
So to calculate the gradient, you count the units to the right (run), and the units up (rise) going from one point to the other, then divide

For this problem,

Sometimes, it is calculated without plotting, so instead of visualizing the rise and run, it is calculated by difference from the coordinates of the points:
For this problem, we could have calculated, without plotting:
