Line AB contains points A (8, −4) and B (1, −5). The slope of line AB is....
shutvik [7]

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} .

4y = 216

Divide by 4

y = 54

Check

36/4 = 54/6

216 = 216 ✅
