If it is from upper left to lower left (left both times),
and it is a rectangular painting and it is not hanging crooked,
The line from upper left to lower left is vertical,
and the slope of a vertical line is undefined.
The slope is the vertical increase divided by
the horizontal displacement to the right,
which in that case is zero, and division by zero is not defined.

Now, for a properly hung rectangular painting with those dimensions,
from upper left to lower right,
you would gain meters in height,
as you moved meters to the right,
for a slope of .

So your rise is 7 and your run is 4? Rise is the vertical, the heght, and run is the horizontal, the width. Generally the rise is smaller than the run, but I'll take your word that your height is 7 and your width is 4.

You say that you want to measure the slope from the UPPER LEFT to the LOWER LEFT. In that case, your slope would be 0 so you have an error.

Review your problem:
- If it says from the left TOP to the right BOTTOM, your slope is negative, it would be -7/4
- If it says from the left BOTTOM to the right TOP, your slope is positive, it is 7/4
Remember, slope is rise over run, it is the measure of how steep a line is. It is height over width, or height over length as it is often called.
