Question

How do you find slope of line passing through (4,6) and (9,-2)?

Answer 1

The slope of a line between two points in the difference in the y coordinate values divided by the difference (taken in the same order) of the x coordinates.

Explanation:

Given the points `(4,6)` and `(9,-2)`
`color(white)("XXXX")` `Delta y = 6 - (-2) = 8`
`color(white)("XXXX")` `Delta x = 4-9 = -5`
slope `= (Delta y)/(Delta x) = -8/5`
