Step-by-step explanation:
Hey there!
The given points are; (1,2) and (-3,-9).
Use slope formula for finding the slope.
[tex]slope(m) = \frac{y2 - y1}{x2 - x1} [/tex]
Put all values.
[tex]m = \frac{ - 9 - 2}{ - 3 - 1} [/tex]
Simplify it.
[tex]m = \frac{ - 11}{ - 4} [/tex]
Therefore, the slope is m= 11/4.
Hope it helps...
