Get some graph paper and draw an x and a y axis:
Start at the point (2,-4):
The numerator of the slope 2/3 is 2, so from that point
draw a line straight up which is 2 units long. That's the
red line below:
The denominator of the slope 2/3 is 3, so from the end of
the red line, draw a line to the right which is 3 units long.
That's the green line below:
Now get a straight edge and draw a line through (2,-4) and the
end of the green line.
That's the line!
[In other problems when the slope is a negative number, the first
line goes straight down the numerator instead of straight up, but
the second line still goes to the right.]
