Question

How do you write the equation in point slope form given (2,-1), m=-3?

Answer 1

See a solution process below:

Explanation:

The point-slope formula states: `(y - color(red)(y_1)) = color(blue)(m)(x - color(red)(x_1))`

Where `color(blue)(m)` is the slope and `color(red)(((x_1, y_1)))` is a point the line passes through.

Substituting the slope and values from the point in the problem gives:

`(y - color(red)(-1)) = color(blue)(-3)(x - color(red)(2))`

`(y + color(red)(1)) = color(blue)(-3)(x - color(red)(2))`
