Question

The slope of the line contains the points (4,-7) and (1,5) is ..?

Answer 1

`-4`

Explanation:

The slope is essentially the gradient of the line:

The formulaic approach to find the gradient of the a line with two given points: `(x_1,y_1)` and `(x_2,y_2)` is

`\frac{y_2-y_1}{x_2-x_1]`

Therefore plugging in the values o the points gives us:

`\frac{5--7}{1-4}=-\frac{12}{3}=-4`
