Question

Find the slope of the line?Ordered pairs (-4, 1) and (1, -2)

Answer 1

The slope of the line is:

`m=-(3)/(5)`

To find the slope of a line with two points, P and Q, the formula is:

`\begin{gathered} P=(x_p,y_p);Q=(x_q,y_q) \\ m=(y_p-y_q)/(x_p-x_q) \end{gathered}`

Then if P = (-4, 1) and Q = (1, -2)

We can replace inthe formula:

`m=(1-(-2))/(-4-1)=-(3)/(5)`
