Question

How do you find the slope of the line passing through the points (0, -4) and (-6, 7)?

Answer 1

See a solution process below:

Explanation:

The formula for find the slope of a line is:

`m = (color(red)(y_2) - color(blue)(y_1))/(color(red)(x_2) - color(blue)(x_1))`

Where `(color(blue)(x_1), color(blue)(y_1))` and `(color(red)(x_2), color(red)(y_2))` are two points on the line.

Substituting the values from the points in the problem gives:

`m = (color(red)(7) - color(blue)(-4))/(color(red)(-6) - color(blue)(0)) = (color(red)(7) + color(blue)(4))/(color(red)(-6) - color(blue)(0)) = 11/-6 = -11/6`
