Question

How do you write the point slope form of an equation for a lint that passes through (9,-5) with m=0?

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)(-5)) = color(blue)(0)(x - color(red)(9))`

`(y + color(red)(5)) = color(blue)(0)(x - color(red)(9))`
