Answer:
\(The\ slope\ of\ the\ line\ AB\ is \frac{1}{7} .\)
Step-by-step explanation:
Formula for slope
\(m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\)
As the Line AB contains points A (8, −4) and B (1, −5).
Put points value in the above
\(m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\)
\(m = \frac{- 5- (-4)}{1 - 8}\)
\(m = \frac{- 5 + 4}{1 - 8}\)
\(m = \frac{- 1}{-7}\)
\(m = \frac{1}{7}\)
\(Therefore\ the\ slope\ of\ the\ line\ AB\ is \frac{1}{7} .\)
