Question

Find the slope of the line that contains the points (3, -6) and (9, 2).

Answer 1

Hello!

To find the slope of line, we will need to use the slope formula.

The slope formula is:
`(y_(2)-y_(1) )/(x_(2)-x_(1))`.

Before the use the formula, we should assign the ordered pairs to
`(x_(1), y_(1))` and
`(x_(2), y_(2))`.

(3, -6) can be assigned to
`(x_(1), y_(1))` and (9, 2) is assigned to
`(x_(2), y_(2))`. With that, we can substitute those values into the formula.

`(2-(-6))/(9-3)= (8)/(6) = (4)/(3)`

Therefore, the slope of the line is 4/3.
