Question

What is the slope of the line through (-10,1)(−10,1)left parenthesis, minus, 10, comma, 1, right parenthesis and (0,-4)(0,−4)

Answer 1

`- (1)/(2)`

Explanation:

We have to find the slope of the line through the points (-10,1) and (0,-4).

We know the formula of slope of a straight line when two different points on the line are known to be (
`x_(1), y_(1)`) and (
`x_(1), y_(1)`) is given by
`[(y_(1) - y_(2)  )/(x_(1) - x_(2))]`.

Therefore, in our case (
`x_(1), y_(1)`) ≡ (-10,1) and (
`x_(1), y_(1)`) ≡ (0,-4)

Therefore, the slope is
`(1 - (- 4))/(- 10 - 0) = - (1)/(2)` (Answer)
