To find slope, subtract the y values over the x values over x values, or
y(1) - y (2) / x(1) - x(2) (note that 1 and 2 should be the same for the same points, so like don't put one y value first and the x value for the same point second)
so we can do:
6 - 4 / 3 - - 3 and solve.
6 - 4 is two, and in 3 - - 3 the negatives cancel each other out and make a positive, so we add 3 + 3, gibing us 6.
so, 2/6 can be simplified to 1/3, meaning the slope of the line is 1/3.
