Answer:
-b/a and line is falling
Step-by-step explanation:
Let (-a,0) and (0,-b) be point 1 and 2, respectively. The slope passing through point (-a,0) and (0,-b) can be calculated using the following equation
[tex]m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-b - 0}{0 - (-a)} = -b/a[/tex]
As b and a are positive real number, then the slope m = -b/a is a negative real number. The line passing through these 2 points is falling.
